COMPOUND PENDULUM (TOM-004)
The length L of the ideal simple pendulum above, used for calculating the period, is the distance from the pivot point to the center of mass of the bob. A pendulum consisting of any swinging rigid body, which is free to rotate about a fixed horizontal axis, is called a compound pendulum or physical pendulum. For these pendulums the appropriate equivalent length is the distance from the pivot point to a point in the pendulum called the center of oscillation. This is located under the center of mass, at a distance called the radius of gyration that depends on the mass distribution along the pendulum. However, for any pendulum in which most of the mass is concentrated in the bob, the center of oscillation is close to the center of mass.

FOUR BAR CHAIN MECHANISM
A four-bar linkage, also called a four-bar, is the simplest movable closed chain linkage. It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar four-bar linkage. If the linkage has four hinged joints with axes angled to intersect in a single point, then the links move on concentric spheres and the assembly is called a spherical four-bar linkage. Bennett’s linkage is a spatial four-bar linkage with hinged joints that have their axes angled in a particular way that makes the system movable.
SINGLE SLIDER CRANK MECHANISM
The slider-crank mechanism is one of the most useful mechanisms in modern technology since it appears in most of the internal combustion engines including automobiles, trucks and small engines. The slider-crank kinematic chain consists of four bodies linked with three cylindrical joints and one sliding or prismatic joint. It is used to change circular into reciprocating motion, or reciprocating into circular motion. The arm may be a bent portion of the shaft, or a separate arm attached to it. Attached to the end of the crank by a pivot is a rod, usually called a connecting rod. The end of the rod attached to the crank moves in a circular motion, while the other end is usually constrained to move in a linear sliding motion, in and out.
DOUBLE SLIDER CRANK MECHANISM
Double slider-crank mechanisms, there are four links connected by two revolute joints and two sliding or prismatic joints. In the double-slider model, a plate is attached to one of the moving links. As the motion proceeds, a piece of chalk fixed to an arm will trace out an exact ellipse. Reuleaux designed adjustments to this model to change the parameters of the ellipse. The trainer is used to convert the linear motion of the piston to rotational motion of the crankshaft.
