Rod OA rotates counterclockwise at a constant angular rate θ˙ = 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=(1.6cosθ)m. Both collars have a mass of 0.55 kg . Motion is in the horizontal plane. Determine the magnitude of the force which the circular rod exerts on one of the collars at the instant θ = 45∘ Determine the magnitude of the force that OA exerts on the other collar at the instant θ = 45∘

Question

Rod OA rotates counterclockwise at a constant angular rate θ˙ = 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=(1.6cosθ)m. Both collars have a mass of 0.55 kg . Motion is in the horizontal plane.

Determine the magnitude of the force which the circular rod exerts on one of the collars at the instant θ = 45∘

Determine the magnitude of the force that OA exerts on the other collar at the instant θ = 45∘

A
r = 1.6 cos 0
e = 4 rad/s
B
0.8 m
Transcribed Image Text:A r = 1.6 cos 0 e = 4 rad/s B 0.8 m
