Under these equilibrium conditions, the force at

Unformatted text preview: B is measured as F 1 . If, at the instant the cord is released, the reaction at B is measured as F 2 , determine the value of I G . The support at B does not move when the measurement is taken. For the calculation, the horizontal location of G must be determined. Given: M 4 kg = F 1 14.6 N = F 2 9.3 N = a 350 mm = g 9.81 m s 2 = Solution: Guesses x 1 mm = I G 1 kg m 2 ⋅ = A y 1 N = 1 rad s 2 = 553...
