My book has the answers as a) 10Nb) 196NBut I can't figure out the proper way to work it out.I figured you start by using torque and the weight of the board plus the forces of each support to make a equation for Fn1. Then once you solve for it go back and make a equation for Fn2. But I'm not getting the answers in my book when I do this. A uniform platform with mass M=30 kg and length L=15 m is placed on twosupports as shown. The distance between the supports is a= 6 m, and force F=%3D340 N is applied as shown with distance b = 4 m. The system is in staticequilibrium.(a) Find normal force FN1 in Newtons.FN1FN2 (b) Find normal force FN2, in Newtons, exerted by the supports on the platform.
