A force P of magnitude 240 N is applied to end E of cable CDE, which passes under pulley D and is attached to the mechanism at C. Neglecting the weight of the mechanism and the radius of the pulley, determine the value of corresponding to equilibrium. The constant of the spring is 4 kN/m, k = and the spring is unstretched when 90 . =

BE 1500 – Fall 2016 HW 4 Due: 9/29/16 (1:30 P.M.) 1. Write a function file that determines the following sum (for all odd n from 1 to 11) using a for loop. The starting point, ending point, and increment should be input to the function file. 2n+2 y=Σ n−2 function [sum1]=HW5P1(a,b,c) sum1=0; for i=a:b:c sum1=sum1+(2^(i+2))/(i-2); end 2 points 0.25 for correct function header 0.25 for comments 0.5 for initializing sum 0.5 for correct for statement 0.5 for correct sum1 statement 2.
