A) A 1-kg mass stretches a spring 5 cm. How far does the spring stretch when it supports 3-kg?
b) Recall that weight is a force and according to Newton's 2nd Law W= mg. Use g = 9.8 m/s^2 to determine the weight of the 1 kg mass.
c) Use your determined weight for the F in the formula (weight is a Force) and Use Hooke's Law F = -kx, rearrange the terms to solve for the spring constant k in units of (N/cm).

The car hoist allows the car to be driven onto the platform, after which the rear wheels are raised. if the loading from both rear wheels is 1380 lb, determine the force in the hydraulic cylinder ab. neglect the weight of the platform itself. member bcd is a right-angle bell crank pinned to the ramp at c. the force is positive if in tension, negative if in compression.
