A specimen of aluminum having a rectangular cross section 9.5 mm × 12.9 mm (0.3740 in. × 0.5079 in.) is pulled in tension with 3
ryzh [129]

Answer:

The resultant strain in the aluminum specimen is 4.14 \times {10^{ - 3}}

Explanation:

Given that,

Dimension of specimen of aluminium, 9.5 mm × 12.9 mm

Area of cross section of aluminium specimen,

A=9.5\times 12.9=123.84\times 10^{-6}\ mm^2A=122.55\times 10^{-6}\ m^2

Tension acting on object, T = 35000 N

The elastic modulus for aluminum is,E=69\ GPa=69\times 10^9\ Pa

The stress acting on material is proportional to the strain. Its formula is given by :

\epsilon=\dfrac{\sigma}{E}

\sigma is the stress

\epsilon=\dfrac{F}{EA}\\\epsilon=\dfrac{35000}{69\times 10^9\times 122.5\times 10^{-6}}\\\epsilon=4.14\times 10^{-3}

Thus, The resultant strain in the aluminum specimen is 4.14 \times {10^{ - 3}}

Answer:

1. Collision- the sudden, forceful coming together in direct contact of two bodies

2. Newton's third law of motion is<em> naturally applied to collisions between two objects</em>. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction.

3. Momentum is the product of a moving object's mass and velocity. When two objects collide the total momentum before the collision is equal to the total momentum after the collision
