Problem 3.1 (15 Points)\ Use the following parameter values in your work:

T_(AB)=77lb,h=16ft,L=7ft,b=4ft

and

d=5ft

.\ Given: Bar OA has a tension of

T_(AB)

applied by cable

AB

.\ Find:\ Do Not keproduce or Repriat:\ a) Use

vec(r)_(OA)

to determine the moment about point

O

due to the tension in

AB

.\ b) Use

vec(r)_(OB)

to determine the moment about point

O

due to the tension in

AB

.\ To save your time, leave your answers with fractional forms.

Use the following parameter values in your work: TAB=77lb,h=16ft,L=7ft,b=4ft and d=5ft. Given: Bar OA has a tension of TAB applied by cable AB. Find: a) Use rOA to determine the moment about point O due to the tension in AB. b) Use rOB to determine the moment about point O due to the tension in AB. To save your time, leave your answers with fractional forms
