Homework Statement
Reproduce the diagram of the beam shown in Figure, and indicate where you would add conceptual pins to convert this to a corresponding determinate beam to allow approximate analysis of the beam.
Using approximate analysis, draw a neat and labelled Bending Moment...
I am confused from when i get that answer of 534, what do i do then?
Do I cross product the =(0, -2.5,1.5) with (1-1-1)
I need to find Ma and not sure where to go from here can you please help me?
(79*cos(15)*3.05)+(50*0.75)+(25*9.81*1.525)= Rb_y*3.05
I am sorry If i am wasteing your time, But is the above what you mean? I am sorry to be so slow but I am very confused about this question.

An old wooden telephone pole with a single cross member was blown off center during a recent storm. To temporarily stabilize the telephone pole, a repair crew has attached a cable from the end of the cross member to an eye-ring stake anchored in the ground. (Figure 3) If...
Sorry if I seem very slow, But is what you are saying is:
(79*cos(15)*3.05)+(50*0.75)+(25*9.81)= Rb_y*3.05
Please correct me if I am still getting it wrong..
(79*cos(15)*3.05)+(50*0.75) = Rb *3.05
Rb=88.6
Ra * sin(53.13010)*3.05 = 50*2.3
Ra=47.1311
I may be very slow, but i do understand what you are saying, however i am haveing trouble to where in this equation(above) does the force from the beam go. Do i just times the weight by 9.81 to find N...
It says that I have already uploaded the image. I have also posted this question in a different forum. Can you please have a look at this one.

Above is the same question with figure.
Sorry for the confustion.
Thanks

If AB has a bearing of following 97° 49' 45" and a anti-clockwise angle from A to C is measured as 71° 6' 12". Calculate the bearing AC (enter as numeric value of ddd.mmss e.g. 100° 20' 30" would be entered as 100.2030).
I am very stuck here and unsure what is really being asked.
