    Indeterminate and determinate beam analysis

    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...

    Wooden telephone pole, Moment (HELP PLEASE)

    so the answer would be the cross product of (534.05,-534.05,-534.05) X (0,-2.5,1.5)?

    Wooden telephone pole, Moment (HELP PLEASE)

    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?

    Roller at point A, Magnitudes

    (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.

    Roller at point A, Magnitudes

    (79*cos(15)*3.05)+(50*0.75)+(25*9.81*0.75)= Rb_y*3.05 I think i read that right. Is that what you mean? ^^^^

    Roller at point A, Magnitudes

    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..

    Roller at point A, Magnitudes

    (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...

    Calculate the bearing

    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. Can...
