A non-linear analog force sensor outputs the following voltages for different forces.

a. Force (N) = 10 15 20 25 30
b. Voltage (volts) | 10 | 20 | 35 | 55 | 80

(a) Use MATLAB to plot the above data points (Voltage vs. Force). (b) You can use curve fitting (using "polyfit" and "polyval", or similar commands, in MATLAB) to find an equation relating the voltage to the force. Implement a curve fitting method and use it to plot Voltage vs. Force from 10 N to 30 N in 0.1 N increments. Display these two plots in the same figure window.

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.

Acertain flow of air (at stp) has a velocity distribution given by v i (in ft/s). if this flow is going through a 4 ft square area in the yz-plane (centered at the origin), what is the mass flow rate (in lbm/s)?

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
