Assume that the masses of the chains, pulleys, and ropes are negligible and the crate is rising with an acceleration of 2.9 m/s2. Determine the force also examine the tension in the upper chain.
The lander is 8.2 meters above the surface and has the downward speed of 0.89 m/s while the engine is cut off. What is the speed of the lander just before it touches the surface.
A 2-2-2 kinematic coupling uses 19-mm silicon nitride balls and tungsten carbide vees. Determine the Hertz contact stresses for a 50 N coupling load. Is this kinematic coupling overloaded? Where are the locations of maximum compressive, shear and ten..
A cue ball (mass = 0.165 kg) is at rest on a frictionless pool table. The ball is hit dead center by a pool stick, which applies an impulse of +1.61 N·s to the ball. Find the velocity of the second ball just after it is struck
Two charges, and are the distance apart. These two charges are free to move but do not because there is a third charge nearby what should be the magnitude of the third charge and its placement in sequence for the first two to be in equilibrium.
