The angular momentum vector of a precessing gyroscope sweeps out a cone as shown in the figure below. The angular speed of the tip of the angular momentum vector, called its precessional frequency, is given by t/L, where ris the magnitude of the torque on the gyroscope and L is the magnitude of its angular momentum. In the motion called precession of the equinoxes, the Earth's axis of rotation precesses about the perpendicular to its orbital plane with a period of 2.58 x 10 yr. Model the Earth as a uniform sphere and calculate the torque on the Earth that is causing this precession. N m

Consider an unsuccessful attempt to take off a tire using a wrench to loosen the bolts. Assume the wrench is 0.3m long and are you able to apply a 200N force  Because the tire is flat you can only apply your force at a 60° angle.  What is the torque at the center of the bolt.    You find a tire jack and are now able to apply 200N of force at an 80° angle.  Is the resulting torque more or less and what is the new torque.

When you hold an ball by only your forearm, the main lifting muscle in your arm is the biceps. Suppose the mass of a forearm with hand is 1.80 kg. The biceps is connected to the forearm a distance of 2.50 cm from the elbow, and it holds a 44.5 N (about 10 lbs) ball at the end of the forearm at distance of 35.0 cm from the elbow. What is the magnitude of the torque about the elbow by the ball, in N·m? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

The angle between the beam and the floor is 15.0 degrees. The angle between the rope and the horizontal is 31.0 degrees. The beam is 4.10-m long and has a mass of 6.10 kg. The box sits a distance of d = 0.770 m from the upper end of the beam and has a mass of 9.60 kg.What is the torque due only to the weight of the box if the axis is at the hinge?

Plz use g = 9.8 m/s2 to find if needed

A rectangular bar is hinged at point O.  The bar is 3.00 m long and 2.00 m wide.   Find the torque resulting from the following force about an axis through point O: F1 = 1 N. Use a positive for a counterclockwise torque and a negative for a clockwise torque.

The body in the figure is pivoted at O. Three forces act on it in the directions shown: FA = 9.30 N at point A, 5.40 m from O; FB = 13.0N at point B, 2.90 m from O; and Fc = 18.0 N at point C, 2.90 m from O. Taking the clockwise direction to be negative, what is the net %3D torque about O? 135° A C 160° 90 FA Units Number i

A simple pendulum consists of a small object of mass 3.0 kg hanging at the end of a 2.0-m-long light string that is connected to a pivot point. (a) Calculate the magnitude of the torque (due to the force of gravity) about this pivot point when the string makes a 8.0° angle with the vertical. N.m (b) Does the torque increase or decrease as the angle increase? increase O decrease Explain.
