Σ Mb = 0 = (0.9231) Fcd (2.5 ft) + (Fx) (7.5 ft) = (2.308 ft) (1560 lb) + (480 lb) (7.5 ft) = 3600 lb ft + 3600 lb ft. Machines: 1. Machines are structures designed to transmit and modify forces. 2. Machines can vary from simple tools to complicated mechanisms. 3. The main purpose of machines is to transform input forces into output. forces. 4. ................
