The 10.0-lb block rests on a surface for which uk = 0.500. It is acted upon by a radial force of 2.00 lb and a horizontal force of 7.00 lb, always directed at 30.0° from the tangent to the path. As the block is rotating in a circular path, the speed of the block increases and as a result the tension in cord AB also increases. If the block is initially moving in a circular path with a speed v1 = 2.00 ft/s at the instant the forces are applied, (A) determine the speed of the block when the tension becomes 20.0

Concept explainers

Types of loading

In mechanical terminology, the term load indicates that external force/weight, either constant or variable, acts on a mechanical member/structure. The weight of an object of a specific material is also an external load, and the external force that works on a structure comes under the categories of loading. The external load generates its effects as stress and strain in the structure.

Question

The 10.0-lb block rests on a surface for which µk =
0.500. It is acted upon by a radial force of 2.00 lb
and a horizontal force of 7.00 lb, always directed
at 30.0° from the tangent to the path. As the block
is rotating in a circular path, the speed of the block
increases and as a result the tension in cord AB
also increases. If the block is initially moving in a
circular path with a speed v1 = 2.00 ft/s at the
instant the forces are applied, (A) determine the
speed of the block when the tension becomes 20.0
Ib and (B) determine the time required for the
tension to be 20.0 lb. Neglect the size of the block
for the calculation.
