Torque and meter stick

Physics lab question: torque experiment the experiment using meter stick and a weight set to explore static equilibrium part i: determine the mass of a typical meter stick without placing it on a scale part 2: using the same meter stick, grasp it with a trigger grip so your trigger finger is located at 10 cm part 3: determine the two forces your hand must apply to the meter stick in order. Torque is the tendency of a force to produce a rotation around an axis in this experiment we will examine the clockwise and counterclockwise torque of a meter stick balanced on a fulcrum there. This is a meter stick on a balance point at the center using the center of the meter stick as the balance means that there is no torque due to the weight of the meter stick on the left side there is a mass hanging a distance l_1 from the pivot this will make a positive torque. Physics 244 9 torque introduction in part i of this lab, you will observe static equilibrium for a meter stick suspended horizontally in part ii, you will observe the relationship between torque, moment of inertia and angular.

Rotational equilibrium introduction: in the past experiments, we have observed several cases of equilibrium, that is, the a total torque of zero is also required for a system to be in rotational meter stick you will place the meter stick on a fulcrum, which is placed at the center of gravity of the meter stick you will then add. Now use the condition that = 0 to find the force being exerted on the meter stick at the pivot point now calculate the sum of the torques about other reference points, such as the 20 cm mark and the 70 cm mark. Move the meter stick in its support so that the new pivot point is 10 cm away from its balance point restore balance by hanging a known mass from one side of the meter stick use the equilibrium condition to determine the meter stick mass and check your result by massing the stick on the pan balance.

The equipment the most basic part of the lab is the fulcrum and meter sticksee figure 5 the fulcrum is mounted to a block of wood and is used as a pivot point for the meter stick there are also three clamps on your table. This is because the meter stick is made of natural wood, so the mass is not evenly distributed across the meter stick a possible method of reconciling the non-centered pivot point is to find the mass per centimeter, and add the torque due to the mass of the meter stick on each side of the pivot point to the net torques. Static equilibrium 5 torque balance in this exercise, the torque due to a system of weights placed along a meter stick will be calculated and tested with the laboratory equipment show your calculations for each case on a separate piece of paper 1 calculate the torque of the meter stick due to a mass of 0010 kg placed 040 m. Students start by balancing the meter stick at its center of mass by hanging a string from a ring stand at this point, the total torque is zero because the meter stick is balanced then, students hang 2 different masses on each side of the balancing point, record their locations, and calculate the torque on the stick.

Plot torque on one side versus torque on the other side now move the pivot point to away from the center of the meter stick add a counter weight to restore balance to the force. Materials meter stick support stand laboratory balance string knife-edge clamp/four knife-edge clamps four hooks weights unknown mass with hooks procedure first the apparatus was to be set up which consisted of a supporting stand, meter stick, and knife edge clamp. A meter stick was used along with one mass and a spring the meter stick was placed at its pivot point to get the system at static equilibrium all of this was done so in the end we could calculate the force of the torque.

What is torque how do you calculate torque an example if you find this useful, you might like my ebook just enough physics - . Best answer: consider the weight of the meter stick as all at its center of gravity, th 50 cm mark let x be the distance from the end of the stick to the edge of the table find the distance from the table edge to the center of the stick and the weight in terms of the extension x the torque around the. A meter stick can be used as a scale as long as you know the mass of the stick you can think of it as a miniature seesaw with only one person on it just as a person can use a seesaw alone as long as he sits with the pivot close to him as seen in figure 1, the mass of a meter stick can be used to balance an attached mass.

torque and meter stick This torque is equal to the weight of the meter stick (w beam) times the 20cm distance that its center of gravity has from the pivot 1) attach 50  0g at 60  0cm, 50  0g at 80  0cm, and on the other side of the pivot, 35 0 g where balance can be reached.

Torques and rotational motion the torque equation for the second picture would look like this initially: t net = t 1 - t 2 if a meter stick balances at the 20 cm mark with 250 grams hung from one end, what is the mass of the meter stick problems: 1. Names: january 29, 2008 torque lab we will use a meter stick and various attachments to look at torque the first task will be to determine the location of the center of mass (cm) of your. If the meter stick is balanced with weight on both ends, what must be true of the torques of both sides 3 if a 200 lb man and a 50 lb little boy are sitting on a teeter -totter, how would you place them so that they would balance.

The meter stick through it until the extended meter stick balances the attached weight (ie level) calculate the total torque about the pivot due to the hanging mass + clamp + 5 g hanger this torque is being balanced by the weight of the meter stick, which acts as if it were all. Torque physics 211 lab the weight of the object acts is at the center of mass of the object so, the first thing we are going to do is the find the center of mass of the meter stick. A) the meter stock is not balanced on the edge of the table and has a torque below is a picture of the meter stick with labels such as the force and lever arm that cause the torque.

Ap physics multiple choice practice – torque 5 a uniform meter stick has a 450 g mass placed at the 20 cm mark as shown in the figureif a pivot is placed at the 425 cm mark and the meter stick remains horizontal in static equilibrium, what is the mass of the meter stick (a) 180 g (b) 450. The weight of the meter stick is distributed all along the stick for the purposes of calculating torques, however, all of the weight of the stick acts as if it were concentrated at the balance point. Theory levers utilize torque to assist us in lifting or moving objects torque is the cross product between a force and the distance of the force from a fulcrum (the central point about which the system turns) the cross product takes only the component of the force acting perpendicular to the distance. Transcript of torque lab according to the two conditions of equilibrium, an object must have (1) a zero net force and (2) a zero net torquefor the meter stick to be in equilibrium, and for it to balance the masses it carries, the torque must be equal -1 meter stick-1 meter stick support and support clip.
