Problem. The pin at C of mass 0.5 kg is pushed by the forked arm AB, which moves in the curved slot whose equation is defined as r= (0.750) m, where 0 is in radians. Assume that at 0= 60° the arm is driven at an angular velocity of d=2 rad/s and an angular acceleration of Ö =3 rad/s². Determine: a) the velocity and acceleration of the pin at C at this instant, and b) the normal force Nc between the pin at C and the curved slot, and the force F exerted by the arm AB onto the pin at C. The motion takes place in the vertical plane. Do not forget to sketch the free-body diagram for the pin!. B Note: v, = † , vo=rð, a,= ï-rö², ag= rö+2rð, tanw= ΣF, - ma, ΣF-maρ dr Ide

Transcribed Image Text:Problem. The pin at C of mass 0.5 kg is pushed by the forked arm AB, which moves in the curved slot
whose equation is defined as r= (0.750) m, where 0 is in radians. Assume that at 0= 60° the arm is driven
at an angular velocity of 0=2 rad/s and an angular acceleration of ö =3 rad/s². Determine:
a) the velocity and acceleration of the pin at C at this instant, and
b) the normal force Nc between the pin at C and the curved slot, and the force F exerted by the arm AB
onto the pin at C. The motion takes place in the vertical plane.
Do not forget to sketch the free-body diagram for the pin!.
