http://homepage.ntlworld.com/russelliott/shifting-cofg-1.png A rigid weightless beam is supported on 3 springs, spaced as marked. The forces in the 3 springs are initially equal (at 10N). The position of the 30N balancing force F to keep the system in equilibrium is determined from taking...

Responding to Lok and Kuruman's points: If I ignore the weights, then the tension in the wire is the force being exerted by the coil spring. For the vertical forces acting on the pulleys and the rest of the system, I've marked the reaction loads. The sum of these loads is 3W. For the...

Homework Statement Three equal weights are suspended from the midpoint of three spans of a near-horizontal negligible-mass wire supported at frictionless pulleys, and are counterbalanced by an adjustable spring set to exert an initial nominal force of 3W, this spring force being increased as...
