Theory of Machine Which of the following statement is correct as regard to the difference between a machine and a structure? All of these The links of a machine may transmit both power and motion, whereas the members of a structure transmit forces only A machine transforms the available energy into some useful work, whereas in a structure no energy is transformed into useful work The parts of a machine move relative to one another, whereas the members of a structure do not move relative to one another All of these The links of a machine may transmit both power and motion, whereas the members of a structure transmit forces only A machine transforms the available energy into some useful work, whereas in a structure no energy is transformed into useful work The parts of a machine move relative to one another, whereas the members of a structure do not move relative to one another 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 (cos α + μ sin α) P = W tan α P = W (sin α + μ cos α) P = W tan (α + φ) P = W (cos α + μ sin α) P = W tan α P = W (sin α + μ cos α) P = W tan (α + φ) ANSWER DOWNLOAD EXAMIANS APP
