Learn that forces can cause objects to turn about a pivot and that the turning effect of a lever depends on the force and its distance from the.

Understand the principle of moments and its application to situations involving one pivot.

Painting of Bighorn sheep(Ovis canadensis):Ovis canadensis canadensis inhabits alpine meadows, grassy mountain slopes and foothill country in proximity to rugged, rocky cliffs and bluffs. Bighorn sheep require drier slopes where the annual snowfall is less than about sixty inches a year, since...

Vector generated image of of Bob Pendulum:This is a weight (or bob) on the end of a massless cord suspended from a pivot, without friction. When given an initial push, it will swing back and forth at a constant amplitude.

Vector generated image of Pendulum:A pendulum is a weight suspended from a pivot so it can swing freely.When a pendulum is displaced from its resting equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When...

Vector generated Image of Digital Thermometer:Ideal low cost replacement for liquid type thermometers. An accurate digital -50ºC to 150ºC thermometer with an accuracy of +/- 1ºC from -20ºC to 50ºC, otherwise +/- 2ºC. A pointed stainless steel probe makes it ideal for reading the temperature...

Vector generated Image of Metal Vane Electroscope: The Metal Vane Electroscope is similar in operation to the standard Gold Leaf type ofelectroscope but, instead of a very thin and fragile leaf of gold deflecting when an electrostatic charge is detected, a light and sensitive aluminium vane...

Painting of Diencephalon and brainstem:The diencephalon is located between the cerebral hemispheres and above the midbrain. .Structures of the diencephalon include the thalamus, hypothalamus, the optic tracts, optic chiasma, infundibulum, Ventricle III, mammillary bodies, posterior pituitary...

Painting of Acromioclavicular joint:The acromioclavicular joint, or AC joint, is a joint at the top of the shoulder. It is the junction between the acromion (part of the scapula that forms the highest point of the shoulder) and the clavicle .The AC joint allows the ability to raise the arm above...

Painting of Atlantoaxial joint:The Atlanto-axial joint (articulation of the atlas with the axis) is of a complicated nature, comprising no fewer than four distinct joints. There is a pivot articulation between the odontoid process of the axis and the ring formed by the anterior arch and the...

Vector generated image of Container Road train--A pickup truck has an inclinable carriage pivotally mounted on the truck chassis. Power means incline the carriage to substantially vertical position.
