nvn: The question does not give the steel plate mass. Also the question does not state what planet this is happening on so to make things easy (you know with rounding up figures and what not), I've decided to assume that it takes place on an Earth like planet where g=10 m/s^2.

thanks tiny tim, a little clearer. I've redrawn the fbd. Is this correct? nvn: I've taken g=10m/s^2 just for ease here.

OK, I'm now even more confused. :confused: The rear wheels will be in equillibrium therefore ∑fx and ∑fy will be 0? By external forces what are you referring to? Isn't that what I've done in my original sketch?

Is the load distributed evenly over the 2 sets of wheels i.e. 150kN over each? I've indicted on the attached picture 250kN for the tension in the cable. Is this correct?

Hi, the problem states; A crane of mass 30,000kg is secured to the end of a steel plate 6 m long. At each end of the plate are a set of wheels. The crane has a jib of length 15m and is required to lift a mass of 25,000kgs from the end of the jib. The jib is positioned over the 6m long steel...
