3. Given the Taylor series expansion for sin x = x − x3/ 3! + x5/5! − x7/7! . Write a program that takes in an arbitrary integer for an angle in degrees, converted the degrees to radians and performs the calculation above. Remember you will need a loop to calculate the ! term and float variables to hold the term(s) in the expansion and the converted degrees to radian.

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.

Apressure vessel with an r/t 20 cannot be treated as thin walled vessel. a)-trune b)- false

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
