A safety valve on the top of a tank containing steam under pressure p has a discharge hole of diameter d(see figure). The valve is designed to release the steam when the pressure reaches the value Pmax If the natural length of the spring, is L and its stiffness is k, what should be the dimension ft of the valve? (Express your result as a formula for h.)
A uniform wheel of 60 cm dia. and weighing 1000 N rests against a rectangular block 15 cm high lying on a horizontal plane as shown in figure. It is to be pulled over the block by a horizontal force P applied to the end of a string wound round the circumference of the wheel. Find the force P when the wheel is just about to roll over the block.
Draw the free body diagram for this problem: The boom of the wall crane 4m long is held at right angles to the wall by a wire that is attached to the wall 3m above the foot of the boom. If the load lifted is 45000N, find the tension in the wire and the compression force in the boom. Neglect the weight of the boom.
A uniform drawbridge must be held at a 38.5 ∘ angle above the horizontal to allow ships to pass underneath. The drawbridge weighs 45000 N, is 13.0 m long, and pivots about a hinge at its lower end.

Find the direction of the force the hinge exerts on the bridge. c) If the cable suddenly breaks, what is the initial angular acceleration of the bridge?
a ladder whose length L is 12 m and whose mass is 45 kg rests against a wall. Its upper end is a distance h of 9.3 m above the ground, as in the Figure. The center of gravity of the ladder is one-third of the way up the ladder. A firefighter whose mass M is 72 kg climbs halfway up the ladder. Assume that the wall, but not the ground is frictionless. What forces are exerted on the ladder by the wall and by the ground?
Three masses are attached to a uniform meter stick, as shown in figure. The mass of the meter stick is 150.0 g and the masses to the left of the fulcrum are m1 = 50 kg, m2 = 75 kg, and m3 that balances the system when it is attached at the right end of the sticky, and the normal reaction force at the fulcrum when the system is balanced. Also, find the mass m3.

A 30kg mass is tied to a uniform rod whose mass and length are 80-kg and 8-m, as shown below. The rod is attached to the floor via a hinge and makes an angle of 70° relative to the ground; a massless string is also attached to the rod at the ¼ point of the rod and makes an angle of 20° relative to the horizontal. What tension must be provided by the rope so that the system remains in stationary? If at some point the string breaks, what will be the angular acceleration of the system the instant that the string breaks?
A uniform trapdoor shown below is 1.0 m by 1.5 m and weighs 300 N. It is supported by a single hinge (H), and by a light rope tied between the middle of the door and the floor.
