Answer:
Effort = 125 N
Explanation:
Given
Load (L) = 500 N
Load distance (L.D) = 20 m
Effort distance (E. D) = 80 m
Effort (E) = ?
We have the formula that
E * E.D = L * L. D
E * 80 = 500 * 20
80E = 10000
E = 10000/80
E = 125 N
If a large animal such as a human being had a thin light exoskeleton, there would be several problems. Since the exoskeleton would not be able to hold its shape, it would be difficult to keep the vital organs protected and the organism would be subject to damaging levels of stress just by moving around.
