Two previously undeformed rectangular specimens of an alloy are to be strain hardened by reducing their cross-sectional areas (rectangular cross-sections will be maintained). For one specimen, the initial and deformed dimensions are 120 mm x 150 mm and 80 mm x 180 mm, respectively. The second specimen, with initial area of 20,800 mm^2 must have the same deformed hardness as the first specimen. a) Calculate the percent cold work (as %; include units in answer) done on the first specimen. b) Calculate the second specimen's area in mm^2 (include units) after deformation.

A 3kg box is displaced at a rate of 5m/s. How much force is required to stop the box in 644.828 microseconds. Include given and solution
Part A U1 = Submit Each blade on a wind turbine is engineered to produce an effective force through its center of mass that is perpendicular to its long axis. (Figure 1) The magnitude of the force produced by each blade in a wind of speed v is F = (40.0 kg/s)v. If the center of mass of each blade is r = 10.2 m, what is U₁, the total work done by the wind turbine's blades, in a wind of speed v = 7.35 m/s after 10 revolutions? Express your answer numerically in joules to three significant figures. ► View Available Hint(s) Part B V ΑΣΦΗ n = Previous Answers Incorrect; Try Again – ΑΣΦ | 1 vec F vec Submit Previous Answers F A brake system is tested by rotating a tire and measuring the number of rotations required for the brake system to bring the tire to a stop. (Figure 2) The tire's radius is R = 50.0 cm and the brake system's radius is r= 19.3 cm. A moment of M = 13.8 Nm is applied to the tire for 5 rotations before the brake system is applied. The brake system is composed of two pads…
In a manufacturing process, a drill press automatically drills a hole into a sheet metal part on a conveyor. In the drilling operation the drill bit starts at rest direcdly above the part, descends quickly, drills a hole, and quickly returns to the start position. The maximum vertical speed of the drill bit is 4 in./s, and while drilling the hole, it must move no more than 2.6 in./s to avoid warping the metal. Let s(t) be the drill biť's height (in inches) above the part as a function of time t in seconds. Sketch possible graphs of the drill bit's velocity [s'(t)] and acceleration [s"(t)].
