A laminated steel spring, simply supported at the ends centrally loaded, with a span of 75 cm is required to carry a proof load of 7.5 kN and the central deflection is not to exceed 5 cm. The bending stress must not be greater than 400MN/m^2. Plates are available it multiples of 4mm for width. Assuming width to be twelve times the thickness and E= 200 GN/m^2. determine suitable values for the thickness width and number of plates and the radius to which the plates should be formed.

In a manufacturing process, a drill press automatically drills a hole into a sheet metal part on a conveyor. In the drilling operation the drill bit starts at rest direcdly above the part, descends quickly, drills a hole, and quickly returns to the start position. The maximum vertical speed of the drill bit is 4 in./s, and while drilling the hole, it must move no more than 2.6 in./s to avoid warping the metal. Let s(t) be the drill biť's height (in inches) above the part as a function of time t in seconds. Sketch possible graphs of the drill bit's velocity [s'(t)] and acceleration [s"(t)].
