A uniform rod of length L and density \(\rho\) is being pulled along a smooth floor with a horizontal acceleration \(\alpha\) (see Fig.). The magnitude of the stress at the transverse cross-secion through the mid-point of the rod is _____...

A particle of mass m moves on the x-axis as follows: it starts from rest at t = 0 from the point x = 0, and come to rest at t = 1 at the point x = 1. NO other information is available about its motion at intermediate times ( 0 < t < 1 ). If...
