Since it is such a beautiful day, Silly Sam is on a swing instead of being at the office. The swing seat hangs from two steel cables, which are fastened to the metal frame using clamps with the bolted connection illustrated below. - The bolt connecting the cable to the clamp has a diameter of 25 mm. - Each of the two bolts connecting the clamp to the swing bar has a diameter of 20 mm. 1. If Sam weighs 197 lb a) What is the shear stress (in psi) in the 25 mm bolt connecting the cable to the clamp? b) What is the axial (tension) stress (in psi) in each of the 20 mm bolt connecting the clamp to the swing bar? 2. If Sam's 24-lb daughter were to sit on Sam's lap. a) What is the shear stress (in psi) in the 25 mm bolt connecting the cable to the clamp? b) What is the axial (tension) stress (in psi) in each of the 20 mm bolt connecting the clamp to the swing bar? Hints: - 25.4 mm = 1 inch Each cable of the swing will carry 50% of the load

Question
Since it is such a beautiful day, Silly Sam is on a swing instead of being at the office. The swing seat hangs from two steel cables, which are fastened to the metal frame using clamps with the bolted connection illustrated below.
- The bolt connecting the cable to the clamp has a diameter of 25 mm.
- Each of the two bolts connecting the clamp to the swing bar has a diameter of 20 mm.
1. If Sam weighs 197 lb
a) What is the shear stress (in psi) in the 25 mm bolt connecting the cable to the clamp?
b) What is the axial (tension) stress (in psi) in each of the 20 mm bolt connecting the clamp to the swing bar?
2. If Sam's 24-lb daughter were to sit on Sam's lap.
a) What is the shear stress (in psi) in the 25 mm bolt connecting the cable to the clamp?
b) What is the axial (tension) stress (in psi) in each of the 20 mm bolt connecting the clamp to the swing bar?
Hints:
- 25.4 mm = 1 inch
- Each cable of the swing will carry 50% of the load
