A ball strikes a homogeneous bar with a force F at a distance h from the pivot point O. The bar has length L and mass m. Determine the distance h such that the horizontal reaction force at O is zero. Can you think of a practical application of knowing this location? ,
The 600 mm long homogeneous slender bar OA has a mass of 8 kg and is supported in the horizontal position by the cable at A and the corner hinge at O
The 600 mm long homogeneous slender bar OA has a mass of 8 kg and is supported in the horizontal position by the cable at A and the corner hinge at O. The cable at A is suddenly released. Just before hitting the incline, the bar has an angular velocity of ω= 5 rad / sec. Calculate the angle θ. Neglect the curvature of the path of the bar mass center when the bar is falling and assume that the...

A seesaw has an irregularly distributed mass of 40 kg k g , a length of 3.0 m m , and a fulcrum beneath its midpoint. It is balanced when a 60-kg k g person sits on one end and a 80-kg k g person sits on the other end. 1. Express your answer with the appropriate units. Enter negative value if the center of mass is located closer to the 60-kgkg person and positive value if the center of...

QUESTION 1 Two skaters, one of mass 80 kg, the other of mass 40 kg, are standing next to each other on frictionless ice rink. The 40 kg skater pushes the 80 kg skater. After the push, the 80 kg skater is going at 1 m/s. How fast and in what direction is the 40 kg skater going after the push? (HINT: use the fact that since there are no external forces, the velocity of the center of mass of...
