Need Torque help

  1. Nov 11, 2004 #1
    Need Torque help!!!!

    I don't understand or even know where to start with this problem:

    A uniform 4.5m long tabletop is supported by pillars 1 meter on each side of the center of the tabletop. The tabletop has a mass of 30kg. A 210lb man sits on one end of the table. Find the force of each of the pillars.

    Can anyone help???? :grumpy:

    First, you need to pick a reference point (I'd recommend one of the ends of the table). Then, you need to calculate the downward forces and torque on the object, and from there you can find the forces of the two pillars. Also, be weary of your units on this problem.
