A cylindrical rod of length 1 m and radius 4 cm is mounted vertically. It is subjected to a shear force of 10^5 ~N at the top. Considering infinitesimally small displacement in the upper edge, the angular displacement of the rod axis from its original position would be : (shear moduli, . G =10¹⁰ ~N / m ^2 )

Options

  1. A1 / 160
  2. B1 / 4
  3. C1 / 40
  4. D1 / 2

Correct answer

A. 1 / 160

Step-by-step solution

aligned & Shear moduli = _ shear & 10¹⁰= 10^5 16 10⁻⁴ 1 & = 1 160 Radian aligned
