Using the diagram in sample problem 7.1 as a model, calculate the tension required in the deltoid with a moment arm of 3 cm from the shoulder, given the following weights and moment arms for the upper arm (u), forearm (f), and hand (h) segments: wt 19 n, wts= 11 n, wt= 4 n, du= 12 cm, de = 40 cm, dh 9. which of the three segments in problem 8 creates the largest torque about the shoulder when the arm is horizontally extended? explain your answer and discuss the implications for positioning the arm for shoulder-level tasks. 64 cm. ( 308 n)

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
