A uniform mass distributed object with a triangular cross-section is free to rotate about the axis shown F in the figure. Four forces with identical magnitudes are exerted on the object. Which one of the forces, if any, exerts the largest torque on the object? 3 Axis of rotation

A seesaw has length 11.0 m and uniform mass 11.3 kg and is resting at an angle of 30° with respect to the ground (see the following figure). The pivot is located at 8.3 m from the end of the seesaw. What magnitude of force (in N) needs to be applied perpendicular to the seesaw at the raised end so as to allow the seesaw to barely start to rotate? F=? 30 N t

The outer cylinder has a radius b = 1.5 m and a mass of 12 kg. On the system act 4 forces. Those shown in figure 2 and a friction force. If the magnitude of the frictional torque is 1.75 mN. Determine: a. The net torque vector on the system. (Magnitude and direction) b. The total moment of inertia of the system

To study torque experimentally, you apply a force to a beam. One end of the beam is attached to a pivot that allows the beam to rotate freely. The pivot is taken as the origin or your coordinate system. You apply a force of F = Fx i + Fy j + Fz k at a point r = rx i + ry j + rz k on the beam. Part a) Calculate the magnitude of the torque, in newton meters, when the components of the position and force vectors have the values rx = 3.71 m, ry = 0.075 m, rz = 0.085 m, Fx = 1.2 N, Fy = -7.6 N, Fz = 1.2 N.  Part b) If the moment of inertia of the beam with respect to the pivot is I = 72 kg˙m^2, calculate the magnitude of the angular acceleration of the beam about the pivot, in radians per second squared.

EXERCISE HINTS: GETTING STARTED I'M STUCK! A man ties one end of a strong rope 7.68 m long to the bumper of his truck, 0.534 m from the ground, and the other end to a vertical tree trunk at a height of 3.86 m. He uses the truck to create a tension of 7.73 x 10 N in the rope. Compute the magnitude of the torque on the tree due to the tension in the rope, with the base of the tree acting as the reference point. N. m

A wrench is used to apply a torque to a bolt. Forces F1 through F6 all have the same magnitude. The point of application of force F1 (and F4) is a distance d from the center of rotation of the bolt. The application points of F1, F2, and F3 are all distance d apart, as shown. Use the convention that counter-clockwise torques are positive; clockwise torques are negative. Determine the torque applied on the bolt by F6 in terms of the variables and angles given in the problem.

A long, thin rod is pinned so that it can rotate about its center. A force with a magnitude of 80.0 N acts a distance d =14.3 cm from the center of the rod, as shown in the figure below. If the force generates a 3.60 N·m torque on the rod, what is the angle θ that the force makes with the rod?
