Tom and Jerry both push on the 3.00-m-diameter merry-go-round shown in (Figure 1). Tom pushes with a force of 50.0 N and Jerry pushes with a force of 33.0 N . What is the net torque on the merry-go-round? Express your answer to three significant figures and include the appropriate units. What is the net torque if Jerry reverses the direction that he pushes by 180∘ without changing the magnitude of his force? Express your answer to three significant figures and include the appropriate units.
(Figure 1) shows a uniform 2.0 kg rod that can pivot in a vertical plane on an axle. We want to find the net torque about the axle. For each of the four forces F 1→1, F 2→2, Fgrav→ and F axle→, is the torque about the axle positive (+), negative (-), or zero (0)?
The figure below shows forces acting at various points on a metal shaft. The angles ? = 48°, ? = 35°, ? = 21°. The length ℓ = 3.6 m. Find the net torque (in N · m) on the shaft about the following axes. An axis through O perpendicular to the page (magnitude and direction) An axis through C perpendicular to the page (magnitude and direction)
Two muscles create tension simultaneously on opposite sides of a joint. Muscle X, attaching 4 cm from the axis of rotation at the joint, exerts 336 N of force. Muscle Y, attaching 3.8 cm from the joint axis, exerts 293 N of force. How much torque is created at the joint by each muscle? What is the net torque created at the joint? In which direction will motion at the joint occur?
The body in the figure is pivoted at O. Three forces act on it in the directions shown: FA = 8.10 N at point A, 5.60 m from O; FB = 16.0 N at point B, 3.90 m from O; and FC = 18.0 N at point C, 3.50 m from O. Taking the clockwise direction to be negative, what is the net torque about O? 8.78 is incorrect.

The answers are provided; please explain the purpose of each equation and why they were used Consider a bar of length 5.5 m, being acted on by three forces and constrained to rotate about its left end. The magnitudes of the first two forces are 19 N and 28 N and the first force is acting on the end of the bar at an angle of 43° What is the torque in newton-meters, due to F1 on this bar relative to the left end? Ans. = 78.87 Nm Equation used: τ1 = rFsinθ What is the torque in newton-meters, due to F2 on this bar relative to the left end, if this force is acting at the midpoint of the bar? Use a coordinate system with positive directed out of the screen. Ans. = 77 Nm Equation used: τ2 = F2 x (L / 2) What is the magnitude of the force F3, in newtons, if the force is a distance 0.85 m from the left end and the bar is not rotating? Ans. = 183.38 N Equation used: F = (τ1 + τ2) / d

A student is trying to determine how much weight can be placed at the 100cm mark on the see-saw without tipping over the see-saw. Answer all questions relative to the rotation point. How much torque is caused by Block A (weight: 2N)? How much torque is caused by the see-saw's 7N weight? How much weight, placed at the 100cm mark would barely balance the see-saw?
Two men are raising a beam as shown. The magnitude of the tension in the right cord is 1000 N, the length of the beam is 5 m, θ=35∘, and ϕ=25∘. If you choose the base of the beam as the origin, and the positive torque direction as counter-clockwise, what is the torque from the right cord on the beam?
