CALCULATIONS

a$)$ Using the given pulley radius and the weight values, calculate the

torque applied to the specimens.

b$)$ Calculate the theoretical angle of twist.

c$)$ Calculate the experimental angle of twist for the specimen by using

the dial gauge readings and the lever distance to where the dial gauge

makes contact.

d$)$ Calculate the maximum torsional shear stress and compare the values

to the shear stress limits of the material and discuss.
