Consider the rotating shaft with imbalances as shown. A single balancing mass is to be located in the same plane as the imbalance masses. Assume the velocity of 10 rad/s m,= 6 kg m₂ = 4 kg m₂ = 4 kg Figures not to scale TT r₁ = 250 mm r₂ = 200 mm r₂ = 200 mm m, 3 60° m3 m₂

The mass of a propeller is 4.5 tons and its centre of gravity is 3.5 mm from the centre of rotation. Find the pull due to centrifugal force when it is rotating at 120 rev/mm

Problem 3: Let P' (mass 4 m) be an attracting particle acting on the system S. The system S is comprised of the 4 colored particles: â₂ â₁ S1 S₁ S2 S3 S4 P' mass = 2.5 m 2 m 3 m 6m mass= 4 m mass= Then, the system S possesses the following characteristics where the distance of each particle relative to P'is given: mass= S3 mass= S₂ 70₁4 dâ₁-2dâ₂ = 70 7-0 = 11da₁-10d â₂ = 6 dâ₁-5d â₂ 70→² = 14 dâ₁ +5dâ₂ 70 = 15 dâ₁-8 dâ₂ S4 OP
