Hey everyone,
Please can someone help me with this question coz I am tryna help out a friend who can't do it but I am completely stumped!
a) Draw an appropriate force diagram for the forces acting at B (only) and use the Sine Rule to show that the tension in the cable is 1.3014kN to 4 decimal places. Determine also the compressive force in the bar, to the same accuracy.
b) Determine the minimum diameter of the cable if the maximum allowable tensile stress in the cable is 17 MN/m^2.
Picture which goes with the question is attached, please can someone help me coz it's driving me crazy! Even telling me what formulae to use would be good coz I'm not a physics student so don't know where to start! Any hints would be much appreciated!
