A flat key is used to connect a pulley to a 45 mm diameter shaft. The standard cross section of the
key is 14 x 9 mm. The key is made of commercial steel (Syt = Syc = 230 N/mm2
) and the factor of
safety is 3. Determine the length of the key on the basis of shear and compression considerations,
if 15 kW power at 360 rpm is transmitted through the keyed joint

1. Calculate the permissible compressive and shear stress. (2m) Calculate the torque transmitted by the pulley. (2m) Determine the length of the key on the basis of shear considerations. (2m) Determine the length of the key on the basis of compression considerations. (2m) V.
Explanation:
I will tell you how this answer is come
the answer is come by solving through cross section
I know you are thinking about what is cross section
cross section means a surface or shape exposed by making a straight cut through something, especially at right angles to an axis.
I know math is quit difficult and boring
but try to understand it
I HOPE IT HELPS
