Theory of Machine In a cam drive with uniform velocity follower, the sharp corners of the displacement diagram are rounded off at the beginning and at the end of each stroke. This is done Because the uniform velocity motion is a partial parabolic motion Because of loose contact of follower with cam surface In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because of difficulty in manufacturing cam profile Because the uniform velocity motion is a partial parabolic motion Because of loose contact of follower with cam surface In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because of difficulty in manufacturing cam profile ANSWER DOWNLOAD EXAMIANS APP
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 = (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 ANSWER DOWNLOAD EXAMIANS APP
