Problem 4.35 • The Situation • Cable Supported Weight = 6ft 3ft = = 2000 lbs= 2 kip • Find Minimum Value for LAC subject to Constraint • TAB & TAC Both ≤2000 lbs
When in Doubt → Plot • Plot TAB & TAC vs LAC • Locate LACmin TAB Limits 4.05 ft
When in Doubt → Plot • Zoom-In on Answer • Locate LACmin more Precisely TAB Limits 4.025 ft
The Command Session >> run Prob4_35_Loaded_Cables Minimum value for LAC in ft = 4.0260 TAB at LACminimum in kip => 1.9993 TAC at LACminimum in kip => 1.7878 Support Angle at LACminimum in ° => 36.8932 index of LACmin => 139
