Physics

A square rod of length L0 = 2.45m and sidelength d = 6.78cm iscompressed with a force of |Fc| = 90.8N in the direction of thelong axis. (a) What is the magnitude of the scalar tensile stress?(b) If we assume that the area of the square rod is approximatelyconstant and its final resting length is L = 2.35m, then what isthe Young's modulus of the square rod? Now assume that the rod isstuck between two slabs that are separated by the sidelength of therod. (c) What is the shear stress when the magnitude of the forceof the top slab on the square rod in the direction of the long axisof the rod is |Fs| = 73.8N? (d) If the total distance that the topof the rod moved, as compared to the bottom of the rod, is ?x =0.206cm, then what is the shear modulus of the rod in thisgeometry?

Starting with all the given valuesA Since the force applied is in the directionof the long axis the only way to measure tensile stress would beto apply it vertically ie on the small squareTensile stress orcompressive stress since the force here is compressing the solidrod is given See Answer
