when the magnitude of the car's overan ULICE v 2. Rotation of bar OA is controlled by the lead screw which imparts a horizontal velocity v to collar C and causes pin P to travel along the smooth slot (Figure 2). Determine the values oft and é, where r= OP, if h = 160 mm, x = 120 mm, and y = 25 mm/s at the instant represented. Figure 2
10 3. The conveyor belt delivers each 12-kg crate to the ramp at A such that the crate's speed is va= 2.5 m/s, directed down along the ramp (Figure 3). If the coefficient of kinetic friction between each crate and the ramp is k = 0.3, determine the speed at which each crate slides off the ramp at B. Assume that no tipping occurs. Take 0 = 30°. -25 m/s 圆圆國國 R 表 B B Figure 3
