Q. A wrecking ball (weight 5400-N) is supported by a boom, which may be assumed to be uniform and has a weight of 3200-N. As the drawing shows, a support cable runs from the top of the boom to the tractor. The angle between the support cable and the horizontal is 32 degrees, and the angle between the boom and horizontal is 48 degrees. Find out the tension in the support cable and find out the magnitude of force exerted on the lower end of the boom by the hinge.
A 346-, uniform, 1.04- bar is suspended horizontally by two vertical cables at each end. Cable A can support a maximum tension of 506.0 without breaking, and cable B can support up to 436.0. You want to place a small weight on this bar. What is the h..
An old trick to find out if a train is coming is to put your ear on the rails of the track. Why is this more effective than just listening for the sounds the train makes in air.
A 4 kg mass is hung from a string which is wrapped around a cylindrical pulley (a cylindrical shell). If the mass accelerates downward at 4.90 m/s2, what is the mass of pulley.
A Volleyball is spiked so that it has an initial velocity of 15 m/s directed downward at an angle of 55 degrees below the horizontal. Find the horizontal component of the ball’s velocity when the opposing player fields the ball?
The displacement of an object moving under uniform acceleration is some function of time and the acceleration. Suppose we write this displacement as s=ka^mt^n, where k is the dimensional constant. Show by dimensional analysis that this expression ..

Two long parallel wires each with a mass per unit length of 25.10 g/m are supported in a horizontal plane by 2.5 cm long strings. Each wire carries the same current, I, causing the wires to repel each other so that the angle between supporting string..
Find the mass flow rate in through the vent in question #1 using the following well-known relationship for the mass flow into an opening:
On your wedding day your lover gives you a gold ring of mass 3.98 g. 59 years later its mass is 3.73 g. On the average how many atoms were abrated from the ring during each second of your marriage? The atomic mass of gold is 177 u.
An underwater diver sees the sun 55 degrees above horizontal. How high is sun above the horizon to a fisherman in a boat above the diver.
A hunter aims directly at a target (on the same level) 101m away. If the bullet leaves the gun at a velocity of 203m/s, by how much will it miss the target.
A 45 kg girl is standing on a 130 kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.33 m/s relative to the plank.
