A beam of rectangular cross section $50$ mm wide and $150$ mm deep is used as a cantilever $6$ m long and subjected to a uniformly distributed load of $2\frac{N}{m}$ over the entire length. Determine the bending stress at $50$ mm from the top layer, at the mid span of the beam. Also calculate the maximum bending stress.bar of $50$ mm diameter and $4$ m long is acted upon by a load of $100$ kN $.$ It is found to extend $100$ mm $.$ Find $($i$)$ stress, $($ii$)$ strain, $($iii$)$ Young's Modulus, and $($iv$)$ Work done.
