r = 16 cos e 6 = 4 rad/s B Rod OA rotates counterclockwise at a constant angular rate 0 = 4 rad/s. The double collar B is pin-connected together such that one collar slides over the rotating rod and the other collar slides over the circular rod described by the equation r = (1.6 cos ) m. If both collars have a mass of 0.5 kg, determine the force which the circular rod exerts on one of the collars...

The slider P can be moved inward by means of the string S, while the slotted arm rotates about point O. The angular position of the arm is given by θ = 0.80t - 0.044t2, where θ is in radians and t is in seconds. The slider is at r = 1.47 m when t = 0 and thereafter is drawn inward at the constant rate of 0.13 m/s. Determine the velocity v and acceleration a of the slider when...

Using a forked rod, a 0.35-kg smooth peg P is forced to move along the vertical slotted path T' = (0.5 0) m, where 0 is in radians. The angular position of the arm is 0 (t)rad where t is in seconds. The peg is in contact with only one edge of the rod and slot at any instant. (Figure 1) Part A Determine the magnitude of the force of the rod on the peg at the instant t =...

1. What is the angular momentum of a 0.240-kg ball rotating on the end of a thin string in a circle of radius 1.35 m at an angular speed of 15.0 rad/s ? 2. A diver can reduce her moment of inertia by a factor of about 4.0 when changing from the straight position to the tuck position. If she makes 2.0 rotations in 1.5 s when in the tuck position, what is her angular speed (rev/s) when in the...

Rod OA rotates counterclockwise with a constant angular velocity of θ = 5 rad/s
Rod OA rotates counterclockwise with a constant angular velocity of θ = 5 rad/s. The double collar B is pin-connected together such that one collar slides over the rotating rod and the other slides over the horizontal curved rod, of which the shape is described by the equation r = 1.5(2-cosθ)ft. (Figure 1) Part AIf both collars weigh 0.80 lb, determine the magnitude of the normal force which the curved rod exerts on one collar at the instant θ = 135°....

So lost!!!!! Help! Problem: Assume that a 1.00 kg ball is thrown solely by the action of the forearm, which rotates about the elbow joint under the action of the triceps muscle, as shown in the figure. the ball is accelerated uniformly from rest to 10.0 m/s in .350 s, at which point it is released. The distance from the elbow to the ball is 31 cm. there is 2.5 cm between triceps muscle and axis of rotation(at elbow). A)...
