Show that motion of a compound pendulum is angular simple harmonic and derive its time period. Ako show that the time period of compound pendulum is minimum when length of pendulum is equal to the radius of gyration. ​

this is poiselle's equation from fluid mechanic in physics. mech eng

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
