hi, solve it please.. Example 22.71. A laminated steel spring. simply supported at the ends and 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 toexceed 5 cm. The bending stress must not be greater than 400 MN/m. Plates are available in md-tiples of 1 mm for thickness and in multiples of 4 mum for width.Assuming width to be twelve times the thickness and E 200 GN/m, determine suitable values forthe thickness, width and rumber of plates and the radius to which the plates should be formed.

The energy required to shear a 1-in. round bar is approximately 1000 ft-lb. In use, the shearing machine is expected to make a maximum of 40 cutting strokes a minute. The frictional losses should not exceed 18 % of the motor output. The shaft carrying the flywheel is to average 150 rpm. (a) What motor horsepower is required? (b) Assuming a size of flywheel and choosing appropriate f C, find the mass and sectional dimensions of the rim of a cast-iron flywheel. The width of the rim is to equal the depth and is not to exceed 3 ½ in. It would be safe to assume that all the work of shearing is supplied by the kinetic energy given up by the flywheel.
