- The double pulley shown in the figure has a mass of 3 kg and a radius of 100 mm rotation. Knowing that when the pulley is at rest, it is applied to the cable in B, a force P of magnitude equal to 24N, determine the speed of the center of the pulley after 1.5 s and the tensile force on cable C.arrow_forwardASAParrow_forwardTwo 2.6-lb collars A and B can slide without friction on a frame, consisting of the horizontal rod OE and the vertical rod CD, which is free to rotate about CD . The two collars are connected by a cord running over a pulley that is attached to the frame at O and a stop prevents collar B from moving. The frame is rotating at the rate 0 =12 rad/s and r= 0.6 ft when the stop is removed allowing collar A to move out along rod OE . Neglecting friction and the mass of the frame, determine, for the position r= 1.2 ft, (a) the transverse component of the velocity of collar A, (b) the tension in the cord and the acceleration of collar A relative to the rod OE.arrow_forward

The angular speed of arm AB that actuates the motion is the constant value = 20 rad/s, so = ct. Determine the forces exerted on the collar by arm AB and the guide bar at x = 1 m. The mass of the collar is 2 kg, and gravitational effects are ignorable.

If the acceleration is a = 13.5 ft/s?, dimensions are di = 0.9 ft, d2 = 0.4 ft, d3 = 1.6 ft, d4 = 1.6 ft, and height h of G2 of the rider is 1.8 ft, determine the normal reaction force under the front skid at point B. Assume there is only traction (horizontal) force under the rear tracks, but no friction force under the front skid. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. Take g= 32.2 ft/s2. a G2 G1 h A В dz da -arrow_forward

If the radius of curvature of the path at B is 1.5 m, and the coefficient of friction between the block and path is 0.3, determine (a) the normal force exerted on the block by the path at B, and (b) the rate of change of speed at this point.

Excluding the children, the merry-go-round has a mass 180 kg and a radius of gyration k₂ = 0.8m. Determine the angular velocity of the merry-go-round if A jumps off horizontally in the -n direction (away from the merry-go-gound) with a speed of 3 m/s, measured with respect to the merry-go-round. After A jumps off, B then jumps off horizontally in the +t direction with a speed of 3 m/s, measured with respect to the merry-go-round - what is the merry-go-round's angular velocity now?

Letting the weights of A and B be 55 and 73 lb, respectively, and letting the static and kinetic friction coefficients between blocks A and B be µi = 0.25, and the static and kinetic friction coefficients between block B and the ground be µ2 = 0.45, determine the accelerations of both blocks.

The double collar B is pin-connected together such that one collar slides over the rotating rod and the other collar slides over the circular hoop rod described by the equation r = 1.6cose m. If the total mass of both collars is 0.5 kg and of the rod and hoop are negligible, when = 30° which takes t = ()(180) sec, determine the circumferential acceleration of the collars, ag.
