Extracted text: Write a function reqZ that accepts two or three inputs. The function should use the equation below to determine the required plastic section modulus Z for a uniformly loaded beam based on the input variables and return that value as the output. Z = 1.67 * w * L^2 / (8 * oy) The inputs to the function will be 1. w - total uniform load 2. L - beam length 3. oy - yield strength if Oy is not provided as an input to the function, use the default value of oy=50e3
