Question

A rotating shaft carries four masses A, B, C and D which are radially
attached to it. The mass centers are 30 mm, 38 mm, 40 mm and 35 mm
respectively from the axis of rotation. The masses A, C and D are 7.5 kg,
5 kg and 4 kg respectively. The axial distances between the planes of
rotation of A and B is 400 mm and between B and C is 500 mm. The
masses A and C are at right angles to each other. Find for a complete
balance, (i) the angles between the masses B and D from mass A,(ii) the
axial distance between the planes of rotation of C and D, (iii) the
magnitude of mass B.

Answer 1

Explanation:

ii) the

axial distance between the planes of rotation of C and D,

Answer 2

The complete balance is 15 mm

i) The angles between the masses B and D from mass A is 65mm

ii) The axial distance between the planes of rotation of C and D 30mm

iii) The magnitude of mass B is 4 radial

Explanation-

The rotating shaft is radially linked to four masses: a, b, c, and d. The mass centers are 30 mm in diameter. 38 mm, 40 mm, and 35 mm away from the axis of rotation, respectively. 7.5 kg, 5 kg, and 4 kg are the masses of a, c, and d, respectively. Between the planes of rotation of a and b, the axial distance is 400 mm, and between b and cis, 500 mm. a multitude of people and a question: Four radially attached masses A, B, C, and D are carried by a rotating shaft. The Rotational Axis. 4 millimeters A rotating shaft has four masses attached to it radially: A, B, C, and D. The mass centers are 30 mm in diameter. 38 millimeters
