Suppose that a 710 kg car is traveling at 13 m/s. Its brakes can apply a force of 4000 N.
What is the minimum distance required for the car to stop? Make a quantitative force
diagram. Write a net force equation for the axis along which the forces are not balanced.

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.
