H = 0.9 m
1. What is the maximum weight, W (N) of a person can footbridge carry?
a. 1265 N
c. 1562 N
b. 1256 N
d. 1526 N
2. If W=800 N, what is the resulting force (N) in the post BD?
c. 300 N
a. 400 N
b. 800 N
d. 900 N
3. If the area of the cable is 113 mm?, how much is the resulting elongation (mm) of the steel cable
due to the maximum tension of 2 kN? Modulus of Elasticity of steel is 200 GPa.
a. 0.25 mm
c. 0.27 mm
b. 0.23 mm
d. 0.29 mm
