Theory of Machine
Which of the following property of the instantaneous center is correct?

The velocity of the instantaneous centre relative to any third rigid link is same whether the instantaneous centre is regarded as a point on the first rigid link or on the second rigid link.

The two rigid links have no linear velocity relative to each other at the instantaneous centre.

A rigid link rotates instantaneously relative to another link at the instantaneous centre for the configuration of the mechanism considered.

All of these

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

T₁/T₂ = μ. θ. n

T₁/T₂ = [(1 - μ tanθ)/(1 + μ tanθ)]n

T₁/T₂ = [(1 + μ tanθ)/(1 - μ tanθ)]n

T₁/T₂ = (μ θ)n

T₁/T₂ = μ. θ. n

T₁/T₂ = [(1 - μ tanθ)/(1 + μ tanθ)]n

T₁/T₂ = [(1 + μ tanθ)/(1 - μ tanθ)]n

T₁/T₂ = (μ θ)n
