ENVI 498 Lecture Notes - Lecture 2: Simple Machine, Linear Motion, Applied Mechanics
mechanism
an assembly of moving parts involved in or responsible for taking an input motion or force and
transforming it to an output motion or force
kinematics
a branch of engineering mechanics that studies motion without regard to force or mass of the things
being moved
dynamics
the branch of classical mechanics that is concerned with the effects of forces on the motion of objects
lever
a machine consisting of a beam or rigid structure with a fixed hinge or fulcrum
pulley
a wheel on an axle that is designed to support movement and change of direction of a cable or belt
along its circumference
wheel & axle
a simple machine generally consisting of a wheel attached to an axle so that motion and/or force can be
transmitted from one to the other.
Inclined plane
A flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising
or lowering a load.
Wedge
A triangular shaped tool used to separate two objects or portions of an object, lift up an object, or hold
an object in place.
Screw
An inclined plane wrapped around a cylinder, a mechanism that converts rotational motion to linear
motion, and a torque (rotational force) to a linear force.

Document Summary
A flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load. A triangular shaped tool used to separate two objects or portions of an object, lift up an object, or hold an object in place. An inclined plane wrapped around a cylinder, a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force. A toothed wheel that interacts with similar components to transfer/change motion from one place to another and/or gain a mechanical advantage. A vector quantity acting on a body (mechanism) causing it to accelerate (move) at a predetermined magnitude (strength) and direction. A straight-line motion that occurs in one direction. The motions of an object around an axel or center point. A gear with a conical shape allowing the axles of the two interacting gears to be oriented at an angle other than parallel.
