The civil engineering students calculate the overall strength of slab. They find that, out to its breaking point, it has sufficient factors for safety for this undertaking. With the bridge in place, they test the slab with a load twice the designed maximum capacity, but still under the designed strength. The bridge slightly sags with the applied load, but when the load is removed, it retains the sag. What is the explanation that fits for the slab material used? A.has been extended beyond its breaking point B.has been extended beyond its elastic limit C.has too large modulus of elasticity D.has too small allowable shear stress

Question
The civil engineering students calculate the overall strength of slab.
They find that, out to its breaking point, it has sufficient factors for safety
for this undertaking. With the bridge in place, they test the slab with a load
twice the designed maximum capacity, but still under the designed
strength. The bridge slightly sags with the applied load, but when the load
is removed, it retains the sag. What is the explanation that fits for the slab
material used?
A.has been extended beyond its breaking point
B.has been extended beyond its elastic limit
C.has too large modulus of elasticity
D.has too small allowable shear stress
