A.The average shear stress in each of the 6-mm diameter bolts and along each of the four shaded shear planes is not allowed to exceed 80 MPa and 500 kPa, respectively. Determine the maximum axial force P that can be applied to the joint.

B. When the hand is holding the 5-lb stone, the humerus
H
, assumed to be smooth, exerts normal forces
F C
and
F A
on the radius
C
and ulna
A
, respectively, as shown. If the smallest cross-sectional area of the ligament at
B
is 0.30 in
2
, determine the greatest average tensile stress to which it is subjected.
