Student Name: …………………………………. Student #: ……………… You have 20 minutes to solve this problem. The tensions in the four cables are equal: | T1 | = | T2 | = | T3 | = | T4 | = T. (a) Determine the value of T so that the four cables exert a total force of | R |=12.5 kips on the support. (b) Express the resultant force R in cartesian vector form and determine the angle between the line of action of the resultant and the x- axis.
