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).

Required information
A piano "string" is steel wire with radius 0.500 mm and
length 1.40 m. It is under 752 N of tension. The density of
steel is 7860 kg/m³ (see table 9.1). The Young's modulus
of steel is 2.00 × 1011 Pa (see table 10.1).
Consider the wire to be a thin solid steel rod. What is the speed of
longitudinal waves (i.e., sound) in the wire? (Longitudinal waves in the
wire do contribute to the characteristic sound of the piano.)

In 1959, Daytona Speed was added to the NASCAR racing circuit and introduced 31° banked curves for racing. This allowed stock cars to reach much higher speeds (around 200 mph) during a race.

The flattest track in NASCAR is Hew Hampshire Motor Speed Way with banked curves of 7° with a turn radius of 410 ft. a) Assuming no friction, what are the max speeds (in mph) without slipping toward the outer edge of the track at the Talladega and NH Motor Speedways? b) With friction (assume μs of 1.1 between the tires and the track)?
