2.2. Solid Circular Shaft Formula

Try these first

1. 1.

   What does the term torsion refer to?

   Hint

   Think about twisting forces applied to different materials.

2. 2.

   What is the formula for calculating shear stress in a solid shaft?

   Hint

   Identify the variables in the formula related to torque, radius, and moment of inertia.

3. 3.

   What is the formula for shear stress in a solid circular shaft?

   • τ = T*r/J
   • τ = J*T*r
   • τ = T^2/r

   Hint

   Remember 'T', 'r', and the importance of 'J' in the formula.

4. 4.

   True or False: Higher torque increases the angle of twist in a shaft.

   • True
   • False

   Hint

   Think about what happens when more force is applied.

5. 5.

   A solid circular shaft with a diameter of 0.15 m is subject to a torque of 300 Nm. Calculate the maximum shear stress.

   Hint

   Remember to compute J accurately.

6. 6.

   A shaft made of steel with a shear modulus of 200 GPa and length of 5 m is twisted with a torque of 400 Nm. Find the angle of twist.

   Hint

   Ensure G is converted to the same unit system used in other values.
