Find out power transmitted by belt:

A belt is running over pulley of 1.5m diameters at 250RPM. The angle of contact is 120º and coefficient of friction is 0.30. If maximum tension in belt is 400N, find out power transmitted by belt.

Sol: Given data

Diameter of pulley(D) = 1.5m

Speed of driver(N) = 250RPM

Angle of contact(?) = 1200 = 1200 X (Π/180º) = 2.09 rad

Coefficient of friction(µ) = 0.3

Maximum tension(Tmax) = 400N = T1

Power (P) = ?

As P = (T1  - T2) X V Watt                                                                                                                             ...(i)

T1 is given, and for finding value of T2, using formula

Ratio of belt tension = T1/T2  = eµθ

400/T2 = e(0.3)(2.09)

T2 = 213.4N                                                                                                                          ...(ii)

We know that V = ΠDN/60 m/sec

V = [3.14 X 1.5 X 250]/60 = 19.64m/sec                                                                 ...(iii)

By putting all the value in equation (i)

P = (400 - 213.4) X 19.64 watt

P = 3663.88Watt or 3.66KW                                                 ......ANS
