[ANSWERED] 1. Determine the principal stresses in the blade implant and the bony material shown in Figure P7–29

1. Determine the principal stresses in the blade implant and
the bony material shown in Figure P7–29 on page 431. Let E
blade
= 20
GPa, v
blade
= 0:30, E
bone
= 12 GPa, and v
bone
= 0:35. Assume plane stress conditions with t = 5 mm.
2. For the 0.5 in. thick canopy hook shown in Figure P7–31
on page 432, used to hold down an aircraft canopy, determine the maximum von
Mises stress and maximum deflection. The hook is subjected to a concentrated
upward load of 22,400 lb as shown. Assume boundary conditions of fixed supports
over the lower half of the inside hole diameter. The hook is made from AISI
4130 steel, quenched and tempered at 400F. (This problem is compliments of Mr.
Steven Miller.)
