For the disk rolling without slipping, if its radius r = 2.0 m, and its angular velocity w = 5.6 rad/s, determine the magnitude of the linear velocity of point B. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point and proper unit. B Your Answer: Answer 45° r No slipping units

Three Wheels. Three rubber wheels are mounted on axles so that they make tight contact with each other and their centers are on a line. The wheel on the far left axle is connected to a motor that rotates it at 35.0 r.p.m.; and drives the wheel in contact with it on its right which, in turn, drives the wheel on its right. The left wheel (Wheel 1) has a diameter of d₁ = 0.22 m, the middle wheel (Wheel 2) has d₂ = 0.32 m, and the far right wheel (Wheel 3) has d3 = 0.48 m. (a) If Wheel 1 rotates clockwise, in which direction does Wheel 3 rotate? (b) What is the angular speed of Wheel 3, and what is the tangential speed on its outer edge? (c) What arrangement of the wheels gives the largest tangential speed on the outer edge of the wheel in the far right position (assuming the wheel in the far left position is driven at 35.0 r.p.m)? (d) What is the largest tangential speed on the outer edge of the wheel in the far right position? (a) (b) Angular speed of Wheel 3: (c) Number Tangential speed…

For the mechanism in the image below, the end A of the bar is moving downward along the slotted guide with a constant velocity va = 2.1 m/s. If r = 0.5 m, determine the angular velocity W of bar AB when 0 = 38°. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point and proper unit. A A ω, α y В
