Theory of Machine The Grubler's criterion for determining the degrees of freedom (n) of a mechanism having plane motion is (where l = Number of links, and j = Number of binary joints) n = 4(l - 1) - 3j n = (l -1) - j n = 3(l - 1) - 2j n = 2(l - 1) - 2j n = 4(l - 1) - 3j n = (l -1) - j n = 3(l - 1) - 2j n = 2(l - 1) - 2j ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine If the rotating mass of a rim type flywheel is distributed on another rim type flywheel whose mean radius is half the mean radius of the former, then energy stored in the latter at the same speed will be One fourth of the first one One and a half times the first one Four times the first one Same as the first one One fourth of the first one One and a half times the first one Four times the first one Same as the first one ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A body of weight W is required to move up the rough inclined plane whose angle of inclination with the horizontal is α. The effort applied parallel to the plane is given by (where μ = tan φ = Coefficient of friction between the plane and the body) P = W tan (α + φ) P = W (sin α + μ cos α) P = W (cos α + μ sin α) P = W tan α P = W tan (α + φ) P = W (sin α + μ cos α) P = W (cos α + μ sin α) P = W tan α ANSWER DOWNLOAD EXAMIANS APP
