Problem 4.51
The force-compression profile of a rubber bumper B is given by FB = Bx, where
B = 3.5 x 10 lb/ft and x is the bumper's compression measured in the horizontal
direction. Determine the expression for the potential energy of the bumper B. In addition,
if the cruiser C weighs 70,00O lb and impacts B with a speed of 5 ft/s, determine the
compression required to bring C to a stop. Model C as a particle and neglect C's vertical
motion as well as the drag force between the water and the cruiser C.

Q2) A loaded Porter governor has four links each 200 mm long and are hinged at a
distance of 40 mm from the axis of rotation. The mass of each ball is 2 kg and
mass of the sleeve is 20 kg. The governor sleeve begins to rise at 300 r.p.m.
when the links are at an angle of 35° to the vertical. Assuming the friction
force to be constant, determine the minimum and maximum speed of rotation
when the inclination of the arms to the vertical is 40°.

A spring with constant k is placed so that its equilibrium position is located a distance h below the bottom of mass m2. There is no friction either in the pulley or between the surfaces of the masses and the platform. When the two masses m¡ and m2 are released from rest, mass m2 begins falling and pulls mass m¡ up the ramp. a) Find an expression for the maximum compression of the spring d caused by mass m2 when it hits the spring. Your answer should be in terms of the m2 variables given (and g). b) On the axes below, make sketches of the kinetic energy (K), gravitational potential energy (Ugav), and elastic potential energy (Ua) of the system as a function of the height of m2, where y = 0 is defined as the point where mass m2 collides with the spring.
