How much torque achieve from 80 X 400 round bar?

Answer 1

To calculate the torque achievable from an 80 x 400 round bar, you need to know the material properties, such as yield strength and the bar's length. The torque (T) can be calculated using the formula ( T = \frac{π}{16} \times τ \times d^3 ), where ( τ ) is the shear strength and ( d ) is the diameter of the bar. Without specific material properties and dimensions, it's impossible to provide an exact torque value. Typically, you would need to consult material strength tables and apply appropriate safety factors for precise calculations.
