Theory of Machine In considering friction of a V-thread, the virtual coefficient of friction (μ₁) is given by μ₁ = μ sin β μ₁ = μ/sin β μ₁ = μ/cos β μ₁ = μ cos β μ₁ = μ sin β μ₁ = μ/sin β μ₁ = μ/cos β μ₁ = μ cos β ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A Hartnell governor has its controlling force (Fc) given by Fc = ar + b, where r is the radius of rotation and a and b are constants. The governor becomes isochronous when a is +ve and b is also +ve a is +ve and b is -ve a is +ve and b = 0 a = 0 and b is +ve a is +ve and b is also +ve a is +ve and b is -ve a is +ve and b = 0 a = 0 and b is +ve ANSWER DOWNLOAD EXAMIANS APP
