A. Determine the average shear stress developed in pin
A
of the truss. A horizontal force of
P
= 40 kN is applied to joint
C
. Each pin has a diameter of 25 mm and is subjected to double shear.

B. The 150-kg bucket is suspended from end
E
of the frame. Determine the average normal stress in the 6-mm diameter wire
CF
and the 15-mm diameter short strut
BD
.

C. The 150-kg bucket is suspended from end
E
of the frame. If the diameters of the pins at
A
and
D
are 6 mm and 10 mm, respectively, determine the average shear stress developed in these pins. Each pin is subjected to  double shear.
