**Assignment on Shear and Tensile Stress Analysis**

**1. Lap Joint Analysis**
- A lap joint is shown, connected by four 20-mm diameter rivets. The load \( P \) is equal to 120 kN and is carried equally by the four rivets.
- **a.** How many shear planes are there?
- **b.** Determine the shear stress in the rivets in MPa.

*Notes:*
- The diagram represents a lap joint with specified distances and load distribution.
- Load \( P = 120 \, \text{kN} \) is applied on each side of the joint.
- The joint includes rivets evenly spaced along the connection.

**2. Tie Rod Analysis**
- A tie rod of \( \frac{1}{4} \) inch diameter is used to hold a plaster wall in place. The tensile stress in the rod caused by load \( P \) is 20 ksi. Find the diameter “d” (to the nearest \( \frac{1}{16} \) inch) of the washer that keeps the bearing stress between the plaster and the washer from exceeding 300 psi.
