The 0.75-lb smooth can is guided along thecircular path using the arm guide. If the arm has anangular velocity θ’= 2 rad./s, and an angular acceleration θ’’= 0.4 rad./s2, at the instantθ= 30°, determine the force ofthe guide on the can. Motion occurs in the horizontal plane.

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. Take g = 9.81 m/s². 0.1 m 0.6 m В А 0.4 m' G 0.4 m D C M Your Answer: Answer units

The pavement compactor is traveling down the incline at VG = 5 ft/s when the motor is disengaged. The body of the compactor, excluding the rollers, has a weight of 8000 lb and a center of gravity at G. Each of the two rear rollers weighs 400 lb and has a radius of gyration of KA = 3.3 ft. The front roller has a weight of 800 lb and a radius of gyration of kg = 1.8 ft. The rollers do not slip as they rotate. (Figure 1) Figure 3.8 ft 5 ft A GT 10 ft 1 of 1 30 730 ▼ Part A Determine the angular velocity of the roller B when the compactor has traveled 16 ft down the plane.

0₁ Oy || 5 Kronk is asked to pull the lever. He applies a force of 20 N, causing the 8 kg lever to have an angular rad velocity of 3 || 6 8 . Determine the angular acceleration of the lever and the reaction forces at O. Assume the lever is a slender rod and that the lever was originally propped up to be level horizontally. The prop was removed at the instant Kronk applied the force. α = 5 Kronk applies the force at a length 7 and the lever has length 1 = 0.2 m. Use negative if CW 1 N N 1 rad 8² F (0) -CCW
