In physics, you can use torque to solve rotational motion problems.

**Solution to torque worksheet #2**

For example, you can calculate how much torque is produced by opening a jar of pickles. How much torque is produced by opening a jar of pickles if the lid on the jar has a radius of 3. Assume that the force is concentrated at one point on the lid. Round your answer to the nearest tenth of a newton-meter. A gram pendulum swings in a clock, never swinging past an angle of 8 degrees with the vertical.

If the pendulum swings on a 2. Just as force always points in the same direction as linear acceleration, torque points in the same direction as angular acceleration. The angle here is 90 degrees because the force is exerted tangentially to the lid:. The force exerted on it at the point of contact with the pendulum is the force of gravity on the pendulum: the weight of the pendulum.

The angle between the two vectors can be seen as either 8 degrees or degrees:. Either number works in the formula, so you can choose to focus on the 8 degree angle. The problem asks you to find the maximum torque — for angles less than 90 degrees, the larger the angle, the larger the sine of the angle will be. So the maximum torque occurs at the maximum angle: 8 degrees.

Therefore, the maximum torque is. Torque in Physics Problems.Torque and Simple Machines. Watch the following presentation before next class and print a copy for your notebook.

Torque Problems On this page I put together a collection of torque problems to help you understand the concept of torque better. The required equations and background reading to solve these problems are given here. What is the torque exerted on the rigid body about point O? See answer Problem 3 In the figure above, consider the force vectors F 1F 2Suppose this situation can be reduced to a resultant force F Racting on the rigid body at point Pwith resultant arm r Rplus a resultant force-couple torque T Ras shown in the figure below.

Write a mathematical equation that equates the torque about point Ofor the two scenarios. See answer Problem 4 Try out this fun experiment related to bicycle physics shown below. Stand a bicycle upright and orient one of the pedals so that it's at the bottom position. Next, push left on the pedal. Which way does the bicycle move? See answer Problem 5 For a rocket in motion, the center of pressure Pcaused by the air resistance at the bottom fins, is the resultant location of the pressure force caused by this air resistance.

Show that the location of P below the center of mass of the rocket, at Gcauses the rocket to be stable in flight, and not tumble through the air. See answer Problem 6 In the pulley arrangement shown in the figure below, a block of mass m is suspended from one end of a rope, and the other end of the rope is connected to a block of mass Mthat is heavy enough to prevent movement. What is the torque exerted at point A, due to the forces acting on rod OA? Assume the pulley has no friction. See answer Problem 7 The torque of a motor is tested using the arrangement shown in the figure below.

This is known as a "prony brake". In this set up, a pair of friction platens is tightened together against the motor shaft, and when the motor rotates in the direction shown, a force is exerted on the scale at point P, via a rod of length L. For a motor speed Sin revolutions per minute, and a scale reading of Win Newtons, what is the power produced by the motor? Answer for Problem 4 The bicycle moves to the left which might be non-intuitive to you.

Even though the force you are applying to the pedal turns the main crank clockwise, which is the direction required to move the bike to the right, the bicycle ends up moving left. This is because the external force F 1 you are applying to the bike, results in a lesser force F 4 in the opposite direction.

Now, if you were to sit on the bike and apply a force F 1 with your foot, the bicycle would move to the right since F 1 is now an internal force in the bike-rider system and hence the only external force acting on the bicycle is F 4 acting on the rear wheel, which pushes the bicycle to the right.

This problem was taken directly from the bicycle physics page. This torque, acting clockwise, rights the rocket back towards the vertical position, which causes the rocket to be aligned with its flight path, and remain stable during flight.Physics Torque Worksheet An important principle observed many times in the study of physics is that of equilibrium where quantities naturally seek a state of balance the balance sought by this simple circuit is equality Any device that could output more power than it took in would violate the law of energy conservation in physics namely that energy cannot transforming values of speed and torque in much the same.
