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 = m/W + C P = C - mW P = mW + C P = mW - C P = m/W + C P = C - mW P = mW + C ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The time of flight (t) of a projectile on an upward inclined plane is(where u = Velocity of projection, α = Angle of projection, and β = Inclination of the plane with the horizontal.) t = g cos β/2u sin (α - β) t = 2u sin (α - β)/g cos β t = g cos β/2u sin (α + β) t = 2u sin (α + β)/g cos β t = g cos β/2u sin (α - β) t = 2u sin (α - β)/g cos β t = g cos β/2u sin (α + β) t = 2u sin (α + β)/g cos β ANSWER DOWNLOAD EXAMIANS APP
