Question

in the arrangement shown incline plane is smooth strings and pulleys are massless find T1 by T2​

Answer 1

For 5 kg block,

50 Sin30° - T1 = 5a -----(1)

For 3 Kg block,

30 Sin30° + T1 - T2 = 3a ----(2)

For 2 kg block,

T2 - 20 = 2a -----(1)

Adding all the equations we get,

20 = 10a

a = 2 ms-²

Putting this in equation (1)&(2) respectively.

50 × 1/2 - T1 = 5 × 2

T1 = 15 N

Again,

T2 - 20 = 2 × 2

T2 = 24

Ratio,

T1/T2 = 15/24

T1:T2 = 5:8 Answer......
