1.What should be the length of an aluminum wire of 6 mm in diameter so it can be twisted one full turn without exceeding a shear stress of 42 MPa? G = 27 GPa.
2.Using the analogy of the pile of sand, determine the ultimate torque resistance for a rectangular section of ax 2a. (Hint: the height of the pile is cyp twice the volume enclosed by the pile gives the required results.)
3.Create a visual, window-based program for multiplying two 3x3 matrices together. Create 18 text boxes for input and 9 text boxes or labels for output
