The block of weight W is originally at rest on the smooth surface. It is acted upon by a radial force { F }_{ R } and a horizontal force { F }_{ H } , always directed at θ from the tangent to the path as shown. Determine the time required to break the cord, which requires a tension T. What is the speed of the block when this occurs? Neglect the size of the block for the calculation. Given: W = 10 lb , θ = 30 deg , { F }_{ R } = 2 lb , T = 30 lb , { F }_{ H } = 7 lb , r = 4 ft , { v }_{ 1 } = 0 ft/s , g = { 32.2ft/s }^{ 2 }
