Mechanical Engineering > GATE 2015 SET-1 > Rolling
In a slab rolling operation, the maximum thickness reduction (Δhmax) is given by Δhmax = μ2R, where R is the radius of the roll and μ is the coefficient of friction between the roll and the sheet. If μ = 0.1, the maximum angle subtended by the deformation zone at the centre of the roll (bite angle in degrees) is ________.
