A rod of length l0 385m and radius r 283cm has one end, Ask an Expert

Academics

A rod of length L0 = 3.85m and radius r = 2.83cm has one end attached to a wall and the other end is being compressed with a force of |F| = 98.5N.

(a) What is the magnitude of the scalar tensile stress of the object?

(b) If we assume that the area of the rod is approximately constant and the applied force compressed the rod to a distance of L = 3.78m, then what is the Young's modulus of the rod?
