The 2.4m wide portion ABCD of an inclined, cantilevered walk-way is partially supported by members EF and GH. Knowing that the compressive force exerted by member EF on the walkway at F is 24.3kN, determine the moment of that force about edge AD of the walkway.
The system is at rest in the position shown, with the 12-lb collar A resting on the spring (k = 20 lb/ft), when a constant 30-lb force is applied to the cable. What is the velocity of the collar when it has risen 1 ft? The collar is attached to th..
