Tanuj Godara 07:03:13 9052-79307 1a) The unit of stress in this particular problem is in pounds per inches squared. This is because you have a unit of pounds (L) in the numerator multiplied by two units of inches (d & c). This is all over a unit of inertia (I), which is inches to the fourth. After simplifying, the result is pounds per inches squared. 1b) = S LcdI L = 700 lbs | c = 6 x .5 = 3 inches | d = 8 ft x 12 = 96 inches | I = 21.4 inches 4 = ( )( . )= S 700 lbs3 in 96in 21 4 in4 . 9420 56 lbsin2 1c) The inputs are L, c, d, and I. These inputs will be used to calculate the output, which is S. The algorithm that I would use is the formula itself, which is = S LcdI

This is shown here: Joulessecond x meterssecondmeters The meters cancel out, leaving you with Joulesseconds2 . 2b) = E hcλ h = 6.6256 x 10-34 | c = 299,792,458 m/s | λ = 5.9 x 10-6 meters = .-( , , )( . - ) E 6 6256 x 10 34 299 792 458 5 9 x 10 6 = 3.367 x 10-20 Js2 2c) The input in this program would only be wavelength, since that is the only value that keeps changing. H and c would remain constant, since they are predetermined measurements or values. The output would be E . In my algorithm, I would have the user input the wavelength by making the wavelength a float....
