8–45. the beam ab has a negligible mass and thickness and is subjected to a triangular distributed loading. it is supported at one end by a pin and at the other end by a post having a mass of 50 kg and negligible thickness. determine the minimum force p needed to move the post. the coefficients of static friction at b and c are mb = 0.4 and mc = 0.2, respectively.

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

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
