A 1.83 m-long aluminum "singing" rod is held in the center by one hand and is stroked along the direction
of the rod by the other. The Young's modulus for Al is
7.00 × 1010 N/m7 and the diameter of the rod is 1.27
cm. If the rod is subjected to a force of 10.5 N, what
is the tensile stress on the rod?

overcharge is the right answer system

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
