Problem statement
The 1/4 lb slider A is pushed along the circular bar by the slotted bar as shown in the figure. The circular bar lies in the vertical plane. The angular position of the slotted bar is θ = 10t² rad. Determine the polar components of the total external force exerted on the slider at t = 0.25 s.
Figure data: circular bar radius of 2 ft; distance from the pivot to the center of 2 ft.
Concepts: slotted bar, slider, radial and transverse components, kinetics of particles
