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-section through the mid-point of the rod is……..

Let A be area of cross section of the rod.
Mass mxx"volume"xx"density =(L/2A)rho
T=-ma=(L/2Arhoa)
Therefore stress T/A=1/2rhoaL
