In a band and block brake, the ratio of tensions on the tight and slack sides of band is given by (where μ = Coefficient of friction between the blocks and the drum, θ = Semi-angle of each block subtending at the centre of drum, and n = Number of blocks)

A.
\(\frac { T_1 } { T_2 } = \mu \theta \times n\) |
|
B.
\(\frac { T_1 } { T_2 } = (\mu \theta) ^n\) |
|
C.
\(\frac { T_1 } { T_2 } = (\frac {1 - \mu tan \theta}{ 1 + \mu tan \theta})^n\) |
|
D.
\(\frac { T_1 } { T_2 } = (\frac {1 + \mu tan \theta}{ 1 - \mu tan \theta})^n\) |
