- Figure 219 shows a compound gear train. Gears B and C are keyed to the same shaft; therefore, they turn at the same speed. Gear A and gear C are driving gears. Gear B and gear D are driven gears. Set up a proportion for each problem and determine the unknown values, x, y, and z in the table. Round the answers to 1 decimal place where necessary.arrow_forwardRepeat Example 5 when microphone A receives the sound 4 seconds before microphone B.arrow_forwarda.

- Which of the following is the equation for Sn term in an AParrow_forwardSet 2: A pork roast was taken out of a hardwood smoker when its internal temperature had reached 180 degrees Fahrenheit and it was allowed to rest in a 75 degrees Fahrenheit house for 20 minutes after which its internal temperature had dropped to 170 degrees Fahrenheit. We will assume the temperature of the roast follows Newton's Law of Cooling, T(t) = Ta +(To-Ta)e-kt, where To is the inital temperature, Ta is the ambient temperature, and k is a decay constant. ("Ambient temperature" means the temperature of the space the object is in.) (a) Find the values of To and Ta for this problem. (b) Find the value of k for this problem. Then write down the function T(t) which gives the temper- ature of the pork roast in degrees Fahrenheit as a function of time t in minutes. (c) Find the time at which the roast dropped to 160 degrees Fahrenheit.arrow_forwardCompare the phase shift and amplitude of y=-cos(x-180∘) and y=-2sin(x-90∘). Which of the following choices is the correct comparison? a The cosine function has a phase shift that is 12 that of the sine function and in the same direction; the amplitude of the cosine function is 2 times that of the sine function. b The cosine function has a phase shift that is 12 that of the sine function and in the opposite direction; the amplitude of the cosine function is 12 that of the sine function. c The cosine function has a phase shift that is 2 times larger than the phase shift of the sine function and in the same direction; the amplitude of the cosine function is 12 that of the sine function. d The cosine function has a phase shift that is 2 times larger than that of the sine function and in the opposite direction; the amplitude of the cosine function is 2 times that of the sine function.arrow_forward
