Im having trouble with torque and equilibrium (independant study unit) and i was wondering if anything woudl be willing to help me with a few text book problems that i just cant solve:(adsbygoogle = window.adsbygoogle || []).push({});

image of problem : http://www.imagedump.com/index.cgi?pick=get&tp=347420

a uniform 1000kg steel girder is supported by the endpoints A and B

What are the upward forces of these end points

Basicaly what i think needs to be done is set up a point of rotation lets say at support B. then the 2 forces of G pushing down have to equal to the force of A pushing up correct?

i just dont rly understand torque that well

For the force of A would it be ?

F x 32m = (9.8 x 1000kg) x 16m ) + (9.8 x 2500kg) x 24m)

16m bieng the distance to the center of the steel girder (Fg) and 24m bieng the distance to the middle of the container (fg)

thanks for the help :)
