A real continuous-time signal xc(t) is bandlimited to frequencies below 5 kHz; i. e., Xc(jΩ) = 0 for |Ω| >= 2π(5000). The signal xc(t) is sampled with a sampling rate of 10,000 samples per second (10 kHz) to produce a sequence x[n] = xc(nT ) with T = 10−4. Let X[k] be the 1000-point DFT of x[n].

a. To what continuous-time frequency does the index k = 150 in X[k] correspond?
b. To what continuous-time frequency does the index k = 800 in X[k] correspond?

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
