PROBLEM NO. 1 An L-shaped rod's position is controlled by a cable attached at B as shown in Figure 1. The rod supports a load of P = 50 lb, create a worksheet or spreadsheet to calculate the tension T in the cable for values of 0 from 0 to 120 using 10 increments. Using appropriate smaller increments, calculate the maximum tension T and the corresponding value of 0. 16 in T 8 in 12 in E B 15 in Figure 1 P 4 in C PROBLEM NO. 2 The position of the 10-kg rod AB is controlled by the block shown in Figure 2 which is slowly moved to the left by the force P. Create a worksheet or spreadsheet that can be used to calculate the magnitude of P for values of x decreasing from 750 mm to 0 using 50-mm increments. Using appropriate smaller increments, determine the maximum value of P and the corresponding value of x. Neglect the effect of friction.

Knowing that the derrick stands in a vertical plane forming an angle with the xy plane, create a worksheet or spreadsheet that can be used to calculate the tension in each cable for values of from 0 to 60 using 5 increments. Using appropriate smaller increments, determine the value of for which the tension in cable BE is maximum. D 1.5 m 1.5 m x E 2 m A Figure 3 Z B 3 m 3 m 3 m C 2000 kg
