The columns whose slenderness ratio is less than 80, are known as
A. Short columns
B. Long columns
C. Weak columns
D. Medium columns
Torque transmitted by a solid shaft is pie/16 *(D^3)*tou
Torque transmitted by a hollow shaft is pie/16 *(D^4-d^4)*tou
Equating two will get 15/16
let me know if I'm wrong
Answer D is right
