Question 2 Solve for the maximum moment (in Nm, 3decimal places) developed in the beam. 80 kN 10 kN/m B C 2m. 8 m Question 4 10 Points What is the minimum diameter of a solid steel shaft that will not twist through more than 2.93° in a 5.52-m length when subjected to a torque of 11.5 kN·m? Use G = 83 GPa ROUND-OFF ANSWER TO 2 DECIMAL PLACE Question 8 10 Points Determine the diameter (in inches, 3decimal places) of a 20ft steel wire (E=29x10 psi) that is suspended vertically from one end and supports a tensile load of 100lb at its lower end. Maximum allowable deformation of the wire is 0.1in.
