Four masses a, b, c and d are attached to a shaft and revolve in the same plane. the masses are 12kg, 10 kg, 18 kg and 15 kg respectively and their radii of rotations are 40 mm, 50 mm, 60 mm and 30 mm. the angular position of the masses b, c and d are 60°, 135° and 270° from the mass a. find the magnitude and position of the balancing mass at a radius of 100 mm.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
