Find out the largest torque, C/C++ Programming

Find out the largest torque:

A flat belt is taken in use to transmit torque from pulley A to pulley B as shown in figure given below. The radius of each pulley is 50mm and coefficient of friction is 0.3. Find out the largest torque that can be transmitted if the allowable belt tension is 3KN.

Sol: Radius of each pulley = 50mm, R1 = R2  = 50mm

R1 = Radius of driver = 50mm

R2 = Radius of driven = 50mm

θ = Angle of contact= 1800 = p,

µ = Coefficient of friction = 0.3

T1 = Allowable tension = 3KN 

T1  greater than T2

Using relation T1/T2  = eµθ

By putting all the value,

3/T2  = e(0.3)(p)

On solving T2  = 1.169KN                                                                       .......ANS

Since Radius of both pulley is same;

So, Torque exerted on both the pulley is same and

= (T1-T2).R1  = (T1-T2).R2

By putting all the value we get,

(3 - 1.169) X 50 = 91.55 KN-mm                                                    .......ANS
