The metal assembly indicated is composed of an upper brass solid cylinder (BC) and a lower solid steel rod (AB). The steel is fixed at point A, and a torque, T, is applied at point C. The maximum allowable shear stress ?max is 10.0 ksi for the brass and 18.0 ksi for the steel. The shear modulus, G, is 5,600 ksi for the brass and 11,200 ksi for the steel. a. Determine the maximum torque T that can be applied without exceeding the maximum shear stress in the steel cylinder. b. If T = 80 kip-inch, what is the smallest diameter brass cylinder which will not overstress the brass? c. Assume the diameter of the steel rod to be 1.5 inches and the diameter of the brass cylinder to be 2.5 inch, and T = 580 kip-inch. What is total rotation at C in degrees?

A steel shaft $left(G_{s}=80 mathrm{GPa} ight)$ of total length $L=3.0 mathrm{m}$ is encased for one-third of its length by a brass sleeve $left(G_{b}=40 mathrm{GPa} ight)$ that is securely bonded to the steel (see figure). The outer diameters of the shaft and sleeve are $d_{1}=70 mathrm{mm}$ and $d_{2}=90 mathrm{mm},$ respectively. (a) Determine the allowable torque $T_{1}$ that may be applied to the ends of the shaft if the angle of twist between the ends is limited to $8.0^{circ}$ (b) Determine the allowable torque $T_{2}$ if the shear stress in the brass is limited to $ au_{b}=70 mathrm{MPa}$ (c) Determine the allowable torque $T_{3}$ if the shear stress in the steel is limited to $ au_{s}=110 mathrm{MPa}$ (d) What is the maximum allowable torque $T_{max }$ if all three of the preceding conditions must be satisfied?

The brass wire has a triangular cross section, $2 \mathrm{mm}$ on a side. If the yield stress for brass is $\tau_{Y}=205 \mathrm{MPa}$, determine the maximum torque $T$ to which it can be subjected so that the wire will not yield. If this torque is applied to the 4 -m-long segment, determine the greatest angle of twist of one end of the wire relative to the other end that will not cause permanent damage to the wire. $G_{\mathrm{br}}=37 \mathrm{GPa}$
An electric drill with a steel drill bit of mass m 527.0 g and diameter 0.635 cm is used to drill into a cubical steel block of mass M 5 240 g. Assume steel has the same properties as iron. The cutting process can be modeled as happening at one point on the circumference of the bit. This point moves in a helix at constant tangential speed 40.0 m/s and exerts a force of constant magnitude 3.20 N on the block. As shown in Figure P20.10, a groove in the bit carries the chips up to the top of the block, where they form a pile around the hole. The drill is turned on and drills into the block for a time interval of 15.0 s. Let’s assume this time interval is long enough for conduction within the steel to bring it all to a uniform temperature. Furthermore, assume the steel objects lose a negligible amount of energy by conduction, convection, and radiation into their environment. (a) Suppose the drill bit cuts three-quarters of the way through the block during 15.0 s. Find the temperature change of the whole quantity of steel. (b) What If? Now suppose the drill bit is dull and cuts only one-eighth of the way through the block in 15.0 s. Identify the temperature change of the whole quantity of steel in this case. (c) What pieces of data, if any, are unnecessary for the solution? Explain.
