5.14. A carriage spring centrally loaded and simply
supported at the ends has 10 steel plates each 5 cm wide by 6 mm thíck.
If the longest plate is 75 cm long, determine the initial radius of curva-
ture of the plates when the greatest bending stress is 800 MPa and the
plates are finally straight. Neglecting the loss of energy at impact, find
the greatest height from which a mass weighing 250 N may be dropped
centrally on the spring without exceeding the limiting bending stress of
800 MPa. Take E = 210 GPa.
