- A long steel rod is placed horizontally between two supports, one at each end. The rod bends a little in the center. Which property of this rod can be used to estimate how much the rod should bend at the center? 1. Its Shear Modulus 2. Its Young's Modulus 3. All of these Moduli can be used to compute how much it bends. 4. Its Bulk Modulus.arrow_forwardIn. 10:03 こ Eと A docs.google.com It is desired to remove the spike from the timber by applying force along its horizontal axis. An obstruction A prevents direct access, so that two forces, one 1.6 kN and the other P, are applied by cables as shown. Compute the magnitude of P necessary to ensure a resultant T directed alo the spike. Also, find T. * 200 mm 100 mm A 150 mm 1.6 kN 1 Add file Submit Never submit passwords through Google Forms.
