A solid circular shaft will be 2 m long, and its diameter is to be determined. It is made of steelwith a shear modulus of 75 GPa, When the shaft is subjected to a torque of 100 Nm, themaximum shear stress is to remain below 10 MPa and the angle of twist is to remain below 3degrees.i.What is the minimum diameter of the shaft which meets the above requirements?ii.Where is the minimum shear stress in the shaft and what is its value?b)Another shaft is a compound circular shaft formed by two circular shafts which are rigidlyattached along their cross-sections at B, as shown in figure Q3(b). The first section of the shaft,from A to B, is a solid cylinder which has a length of 50 cm and a diameter of 3cm. The secondsection of the shaft, from B to C, is a hollow cylinder with a length of 100 cm, an outer diameterof 3cm and an internal diameter of 2cm. This whole shaft is subjected to a torque of 200 Nm.The material in both sections of the shaft has a shear modulus of 85 GPa.Determine the total angle of twist in degrees in the shaft from A to C.ii. If instead the entire 150 cm shaft length was hollow with the same internal and external diametersas the section from B to C, would the total angle of twist increase or decrease?

A bookshelf needs to be built to hold 200 novels. The depth, width and height of the largest novels are 8 inches by 2 inches by 10 inches, respectively and the novels need to sit in the bookshelf so that the largest novel fits perfectly without any overhang of shelf showing. The homeowner would like 4 shelves to hold all the books, with one extra shelf to hold future books (5 total shelves). Each of the four shelves will hold 50 books. The homeowner wants no more than one-inch thick wood shelving. Create an orthographic scale drawing of the bookshelf on grid paper. Be sure to include the front, side, and top views. Include a scale.

Your professor has recruited you to work in her lab to help her win the Nobel Prize. It is critical that your work be as accurate as possible. Rather than using the stated volumes of glassware in the lab, you decide to calibrate each piece. An empty 10-mL volumetric flask weighed 10.263 4 g. When filled to the mark with distilled water at 208C, it weighed 20.214 4 g. What is the true volume of the flask?
