Explain with neat sketch working principle of epicyclic gear train.
Three masses 10 kg, 20 kg and 15kg are attached at a point ........
State the applications of (i) Band brake (ii) Disc brake (iii) Internal expanding shoe brake (iv) External shoe brake
Compare cross belt drive and open belt drive on the basis of.......
The crank and connecting rod of steam engine are 0.5m .......
Discuss the following motion of the follower by drawing the displacement velocity and acceleration diagram.
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
