The mass of the pulley and the mass of the wire are assumed to be negligible. To the mass m₂, it is attached a simple pendulum with a point mass m3 and an inextensible thread of length I and negligible mass. The pendulum swings freely in the vertical plane and the system is subject to the earth's attraction. We study the motion of the system in the inertial reference frame R(O, x, y, z). We note (X₁, Y₁, Z;); i = 1,2,3 as a system coordinates of masses m. We put: m₁ = m₂ = .m; m3 = m.

Two blocks with masses m1 = 5.0 kg and m2 = 7.0 kg are attached by a string as shown in the figure below, over a pulley with mass M = 2.0 kg. The blocks are released from rest. The pulley, which turns on a frictionless axle, is a hollow cylinder with radius 0.050 m over which the string moves without slipping. The horizontal surface is frictionless. Find the speed of the system when the block of mass m2 has dropped 2 m.
Forming a shock absorber, two springs of equal length are nested together. If the maximum compression of the springs is 0.25 and the outer spring has a stiffness of Ka = 420 N/m, what stiffness is required of the inner spring Kb? The design of the spring system is such that if a mass of 2.5 kg is at rest, then dropped from a distance of 0.75 m above the springs, the spring system will catch and stop the mass.
Block A (m = 5 kg), seen in the figure, sits on a smooth surface and is attached by a slender rod to a ball-and-socket joint at B. If the moment and force shown are simultaneously applied to the block, what will the speed of the block be after 4 seconds (starting from rest)?
In a porter governor the mass of the central load is 18 kgand the mass of each ball is 2kg. the top arms (254) mm while the bottom arms are (304) mm long. The friction of the sleeve is 20 N.

A min cage of mass 4t is to be raised with an acceleration of 1.5m/s2 by a cable passing over a hoist drum of 1.5m diameter. What is the power required when the load has reached a velocity of 6m/s, neglecting the inertia of the drum and weight of the cable, but allowing for bearing friction torque of 3kN at the drum? What is the power required at a uniform velocity of 6m/s
A spherical ball of mass 0.2 kg and radius 0.1 m was released from the top of aplatform with an initial velocity of 0m/s as shown in the figure below. The height of theplatform is 4 m and the diameter of the circular loop in the middle is 3 m. Assume thetrack is frictionless and there is no air resistance. (a) What is the velocity of the ball when it reaches the bottom of the slope (whenheight = 0 m and before entering the loop)?(b) What is the velocity of the ball, if it reaches the top of the loop? Will the ballmake the loop?(c) Now, ignore the presence of the loop. The ball falls via the same loop fromposition 1 and directly roll towards position 4, bypassing the loop entirely. Theheight of the hump at position 4 is 1 m. The ball just about lifts off contact fromthe track as it passes through position 4 at top of the hump. What is the radiusof the curvature of this hump?(d) What are the kinetic energies of the ball, when it is at positions 2, 3 and 4?
The double pulley shown in the figure is formed by two wheels that are coupled to each other. The complete pulley (formed by the two wheels) has a mass of 15 kg and a turning radius of 110mm. Block A has a mass of 40 kg. If a force of 2 kN is applied to the tied rope of the inner pulley wheel, determine the speed of block A after 3 seconds. At the beginning, the whole system was at rest. Disregard the mass of the string and consider that the moment of inertia (kg.m²) of the complete pulley is given by IP = mko²where m is the mass of the pulley and Ko is the radiusspinning

A particle M1, weighing 2.4 Ibs, is tied to a thread and describes a circular path in a horizontal plane. The thread, of negligible mass, passes through a hole in the center of the circle and descends vertically. Another particle M2 is attached, weighing 5.0 Ibs, as shown in the figure. If M1 describes a uniform circular motion, with angular velocity w 3.1 rad/s, determine the radius R of the circumference in inches.
Calculate the expected acceleration (Eq. 2) and the experimental acceleration (Eq. 3). This hanging mass will supply the unbalanced (net) force acting on the cart. The track is assumed to be frictionless, so the only force present is that from the hanging mass. m1 (hanging mass), m2 (cart).
