A pulley is driven by the flat belt running at speed of......
Flat belt speed = V = 600 m/min = 600/60 m/sec = 10 m/sec;
Power transmitted = P = 4 kW ;
Coefficient of friction =µ = 0.3;
Angle of lap = θ =1600
Belt tension ratio = T1/ T2 = eµθ = e 0.3(160x π/180) = 2.31; T1/ T2 = 2.31;
T1= T2 x 2.311--------------------------------(1)
P = ( T1 - T2) x V ; --------------------------------(2)
P = ( T2 x 2.31- T2)x 10; Putting value of power
P = 4 kW 4 x1000 = ( T2 x 2.31 - T2)x 10;
T2 = 305.34 N
T1 = 705.34N
