Engineering Mechanics Angle of friction is the Angle between normal reaction and the resultant of normal reaction and the limiting friction The ratio of minimum friction force to friction force acting when the body is in motion The ratio of minimum friction force to the friction force acting when the body is just about to move Ratio of limiting friction and normal reaction Angle between normal reaction and the resultant of normal reaction and the limiting friction The ratio of minimum friction force to friction force acting when the body is in motion The ratio of minimum friction force to the friction force acting when the body is just about to move Ratio of limiting friction and normal reaction ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The law of the machine is (where P = Effort applied to lift the load, m = A constant which is equal to the slope of the line, W = Load lifted, and C = Another constant which represents the machine friction.) P = mW - C P = C - mW P = mW + C P = m/W + C P = mW - C P = C - mW P = mW + C P = m/W + C ANSWER DOWNLOAD EXAMIANS APP
