FBD and Force Balance of the Cart:-
Where R1 and R2 are the reaction forces on the disc.
Also the height of the cart is considered to be very small when compared to the Radius of the Disc.

A pendulum is attached to the cart that has a mass of 3m and that is free to move along the horizontal direction. From the rest condition, when the lumped mass m of the pendulum makes a 0 angle with the vertical, the pendulum is released. 3m L m Compared to the case in which the cart is fixed (it cannot move), when 0=0°, the speed of the lumped mass at the tip of the pendulum would be smaller.

Consider a uniform disk of mass m, and radius R that is rolling with slipping. The surface has a coefficient of kinetic friction a) Find the equations of motion. b) Next consider the same disk when it is rolling without slipping. Find the EOM using either x or θ. Hint: be careful with the generalized force for θ. If we label point P as the point on the disk...
Q7 (15 points): A solid cylinder of mass 5 kg and radius R 0.15 m rolls without slipping on a horizontal surface and is accelerated to the right by a constant force F of magnitude 6 N that is applied at the cylinder by a massless rope as shown in the below figure. Find a) the magnitude of the acceleration of the center of mass of the cylinder, b) the magnitude of the angular acceleration of the cylinder about the...

RP7-17) A light flywheel rotates freely on a shaft located at its center (point o). The flywheel is attached to two masses as shown in the figure. Mass A (mA = 50 kg) is attached to the inner radius (r; = 10 cm) of the flywheel though an inextensible rope. Mass B (m3 = 20 kg) slides along a rough horizontal surface (uk = 0.3) and is attached to the flywheel's outer radius (r = 20 cm) through an inextensible...
Consider the following mass distribution where the x- and y-coordinates are given in meters: 5.0 kg at (0.0, 0.0) m, 3.3 kg at (0.0, 3.5) m, and 4.0 kg at (2.9, 0.0) m. Where should a fourth object of 7.5 kg be placed so that the center of gravity of the four-object arrangement will be at (0.0, 0.0) m? A 1.25 kg solid, uniform disk rolls without slipping across a level surface, translating at 4.00 m/s. If the disk's radius...
We wish to determine the moment at the shoulder that is required to perform the arm motion (shoulder abduction) depicted in Figure 3 below. This motion may be modelled with a simple, single- element linkage system as shown in the figure. The shoulder joint is represented by a simple pin support centred at O. The arm and the carried weight are represented as a rigid body consisting of a rod and a cuboid. In the rigid body model, the length...

Part (a) [2 marks]
The angular displacement of the rigid body ranges from
θ = 0° (the vertical as shown in the figure) to θ
= 135° and can be modelled using simple harmonic motion. Assuming a
rate of 20 [reps/min], write down an expression for angular
displacement, θ [rad] as a function of time, t [s]. You may assume
that the motion starts with an angular displacement of 135°.
Hint: The angular displacement, θ can be expressed as...
