A crane has an arm length of 20 m inclined at 30deg with the vertical. It carries a container of mass of 5 ton suspended from the top end of the arm. Find the torque produced by the gravitational force on the container about the point where the arm is fixed to the crane. Given: 1 ton = 1000 kg; neglect the weight of the arm. Hint: take the force and perpendicular distance from the point where the arm is fixed to the crane. Note: Express your answer in whole number. No unit is required for the final answer. Set your calculator in radians. ...

Assume a single 300-N force is exerted on a bicycle frame as shown in Figure OQ10.5. Consider the torque produced by this force about axes perpendicular to the plane of the paper and through each of the points A through E, where E is the center of mass of the frame. Rank the torques A, B, C, D, and E from largest to smallest, noting that zero is greater than a negative quantity. If two torques are equal, note their equality in your ranking. Figure OQ10.5

What three factors affect the torque created by a force relative to a specific pivot point?
An automobile engine can produce 200Nm of torque. Calculate the angular acceleration produced if 95.0 of this torque is applied to the drive shaft, axle, and rear wheels of a car, given the following information. The car is suspended so that the wheels can turn freely. Each wheel acts like a 15.0-kg disk that has a 0.180-m radius. The walls of each tire act like a 2.00-kg annular ring that has inside radius of 0.180 m and outside radius of 0.320 m. The tread of each tire acts like a 10.0-kg hoop of radius 0.330 m. The 14.0-kg axle acts like a rod that has a 2.00-cm radius. The 30.0-kg drive shaft acts like a rod that has a 3.20-cm radius.
Can a set of forces have a net force that is zero and a net torque that is not zero?
In order to get his car out of the mud, a man ties one end of a rope to the front bumper and the other end to a tee 15 m away as shown below. He then pulls on the center of the rope with a force of 400 N, which causes its center to be displaced 0.30 m, as shown. What is the force of the rope on the car?

Batman has a mass of 0.950kg and is hanging vertically from a light cord that runs over a cylindrical pulley with a mass of 0.350kg placed at the top of an inclined plane that makes an angle of 60.0° with respect to the horizontal. His enemy, Joker, who has a mass of 0.600kg, is laying on the smooth incline holding onto the other end of the cord that Batman is holding on to while hanging off the back of the incline. What will be the magnitude of the acceleration of Batman and Joker?
Which of the following statement/s is/are accurate? For non-uniform body, the center of gravity is at the geometric center. In equilibrium, the net moment of force at the center of gravity is zero. For uniform body, the center of gravity and centroid act on the same point. The center of gravity is always at the geometric center.
