Q1 A circular plate of mass 58kg has an unbalanced mass of 4

Q1. A circular plate of mass 5.8kg has an unbalanced mass of 400g attached to it at a radius 200mm. The assembly is then rotated at 240rpm. Determine: a) bearing reaction and its angle when the angle made by the unbalanced mass is 45 deg. (ANS-43.7N, 145 deg) b) maximum bearing reaction. (ANS-111.35N)

ONLY SOLVE THIS QUESTION - Q2 - Solve problem Q1 again if the plate has added an additional out of balance mass of 200 g located at radius 300mm and at 120° (anticlockwise) to the 400 g mass.

ANS. a) 17.3N @ 87.1° b) 108.3N please show working

Solution

a) 17.3N - 87.1° b) 108.3N
