Mechanical Properties of Solids

There are three types of matter- solid, liquid and gas. Out of them, solids have a rigid shaped and size. The intermolecular forces of attractions in solids are greatest. Mechanical properties are the physical properties of a material which it shows, when it is provided with certain amount of force or load. These properties are to be kept in mind for various purposes. When a force is applied to an object, the object may or may not get deformed depending upon its elastic property. But every time the object develops a restoring force against the force applied. This is commonly known as stress. If the object changes its dimensions due to the force applied it develops strain ( which is the ratio of change in dimension to the original dimension).

Question

a. Two strips of metal are pinned together as shown, with a rod of 10mm
diameter. The Ultimate shear stress for the rod is 60MPa. Determine the
maximum force required to break the pin.

b)
Two students are watching an action film in which a car drives down a ramp onto the back of a
moving lorry. Both are moving at high speed, the car slightly faster than the lory.
One student complains that this is impossible because the car would not be able to stop before
hitting the cab of the lorry.
The car has mass 1250 kg and is moving at a speed of 28.0 ms. The lorry has mass 3500 kg
and a speed of 25.5 ms. The length of the flat back of the lorry allows a braking distance of
5.0 m.
By considering both momentum and energy show that the stunt is possible, provided a
minimum force of about 600 N slows the car down. You should support your explanations with
