Question

A massless uniform rod is subjected to force F at its free end as shown in figure.The ratio of tensile stress at plane P1 to stress at P2 is?

Answer 1

We know, tensile stress= Force/Area

 If two force is applied at the both end of the rod, then Tensile stress would be = Fcosθ/Asecθ

But cosθ=(1/secθ)

     So, tensile stress= (F/A)cos²θ

Answer 2

Answer:

ratio of P1 to P2 is 1:4.
