A plate is fastened to a fixed member by four 20-mm-diameter rivets arranged as shown in Fig. P-333. Compute the maximum and minimum shearing stress developed.
radial distance p from the centroid of the rivet group.

Solution 332
The shearing stress on each rivet is P/A
T = Tp/J
Where:
T = PRn
p= R
J = EAp? = AR'n
%3D
PRn(R)
T =
AR?n
T=
- ok!
A
This shows that 7 = Tp/J can be used to find the shearing stress at the center of any rivet.
