In mechanics, stress is a measure of the internal forces acting within a deformable body. Quantitatively, it is a measure of the average force per unit area of a surface within the body on which internal forces act. These internal forces are produced between the particles in the body as a reaction to external forces applied on the body. In materials without microstructure (these are materials whose microstructure does not play an important role in the mechanical deformation), these internal forces are distributed continuously within the volume of the material body, and result in deformation of the body's shape. Beyond certain limits of material strength, this can lead to a permanent change of shape or physical failure. The dimension of stress is that of pressure, and therefore the SI unit for stress is the pascal (Pa). A three-dimensional stress eld in a material can be represented as a sym- metric matrix of the following form:
where the diagonal terms represent tensile or compressive stresses and the o-diagonal terms represent shear stresses.
A 30-g car rolls from a hill 12 cm high and is traveling at 154 cm/s as it travels along a 275 cm horizontal track. What is the momentum of the car?
short answer
Why does heat cause matter to expand? Water contracts as it cools, like all other liquids, unless it reaches a temperature of about 4 degrees Celsius, at which point it enlarge

Forging: Forging is shaping of metal either by impact or steady compression among a hammer or ram and anvil. Related to hammering or pressing of metal, the main difference among
So I have a question here and I am totally lost: A car starts from rest and accelerates at a constant rate of 1.1 m/s2. If the radius of the car wheels is 29.0 cm, and the final an
