Also when we were calculating our percent error, we weren't comparing the net torques because our theoretical value was 0 and we cannot have a 0 in a denominator.

We solved to find what the mass of the meter stick is and compared it to the actual mass. Upon completion of the lab, one obtained a better understanding of rotational torque and center of gravity.

The mass of the clamp that holds the meter stick is irrelevant because it is keeping the meter stick in equilibrium.

This question can be answered by conducting a force analysis using trigonometric functions. What torque balances the torque due to the weights hanging on the cm mark?

What is the angular acceleration experienced by a uniform solid disc of mass Torque and equilibrium lab physics kg and radius 0.

Since the angle between the cables is degrees, then each cable must make a degree angle with the vertical and a degree angle with the horizontal. Horsepower relative to weight on the other hand is more relevant to the maximum speed of a vehicle.

Adjustable gearing allows sufficient torque to be delivered to the wheels at any given rotational speed of the engine. The principle is that as the angle with the horizontal increases, the amount of tensional force required to hold the sign at equilibrium decreases. Relationship of available torque to rotational speed for different sources.

We would have to conclude that this low margin of experimental error reflects an experiment with excellent results.

The stick here is not affected by the clamp's mass, it is simply balancing about that point. The points of equilibrium in rotational torque were able to be analyzed in multiple contexts. Where r is the vector from the axis of rotation to the point on which the force is acting.

We calculated our center of mass to be at It is also its center of gravity since the gravitational field is uniform.

The data in the table above show that the forces nearly balance. Objects that have most of their mass near their axis of rotation have a small rotational inertia, while objects that have more mass farther from the axis of rotation have larger rotational inertias.

Assume the disc spins about its center. The lever arm would be the distance from the center of gravity to where the mass, or force, is at.

We changed our third mass on the left side with a new unknown mass. The torque rotates about an axis, that we called the pivot point. Keep the meterstick clamped at its Center of Mass. The use of adjustable gearing is necessary to obtain good performance in vehicles powered by combustion engines.

We weren't able to prove the last scenario to be true.

We found it to be at The larger the net force, the greater the linear or translational acceleration, and the larger the mass of the object, the smaller the translational acceleration.

It is often necessary to increase or decrease the torque produced by a motor to suit different applications. The upward force coming from the stand must pass through the center of mass for the stick to be balanced.Physics - Equilibrium Torque Lab. Purpose: To find the mass of an object using only a meter stick, a fulcrum, and two known masses.

Background: Torques are forces applied at a distance from an axis of rotation. Torques are cross product vectors that follow the right-hand rule. A system of torques that sum to zero do not cause rotation. The magnitude of torque depends on how much force is applied, the length of the lever arm that connects the axis to the point where the force is applied, and the angle between the force vector and the lever arm.

The distance is the moment arm, often denoted by r. It is a vector pointing from the. Torque is a force applied at a distance (torque = force * lever arm).

Similar to the balance of forces, torques acting on a body must also sum to zero in order for the body to be in static equilibrium.
