The 0.6-lb particle is guided along the circular path using the slotted arm guide. Motion occurs in the horizontal plane with negligible friction. Note that the circular part of the slot has the radius equal to 0.5 ft, and the radial position, r, is measured from the hinge and the angle is measured in the counter-clockwise direction. If the arm has an angular velocity = 4 rad/sec and an angular acceleration 6 - 8 rad/sec² at the instant when 0 = 30°, determine the force of the arm guide on the particle at the instant. Present your answer in lb using 3 significant figures. 0.5 ft 0 0.5 ft.
At the instant shown, link CD rotates with an angular velocity of W = 9.0 rad/s. If it is subjected to a couple moment M= 320 N-m, determine the magnitude of the vertical reaction force developed on pin D. The block has a mass of 50 kg and center of mass at G. Neglect the mass of links AB and CD. (Hint, since the mass of link AB or CD is negligible, the external force or moment acting on it sums up to 0.) Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point, and proper unit.
