**Question:**As one stretches a metal wire, which condition is reached first?**Options:**- ○ the elastic limit- ○ the proportional limit- ○ the breaking point**Explanation:**In the context of material physics, when a metal wire is stretched, it exhibits different mechanical properties and behaviors. Understanding these limits is crucial for applications in engineering and physics.1. **Proportional Limit:** This is the point on a stress-strain curve up to which the material exhibits elastic behavior and Hooke’s Law is applicable. It is the first condition reached when starting to stretch the wire.2. **Elastic Limit:** Beyond the proportional limit, the elastic limit is the maximum amount of stress a material can withstand and still return to its original shape after the load is removed. It is slightly beyond the proportional limit.3. **Breaking Point:** This is the point where the wire ultimately fails and breaks. It is the last condition and occurs after both the proportional and elastic limits are surpassed.

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).

Consider a metal bar of length L, cross-sectional area A, and Young's modulus Y. When a tension force F is applied to the bar, it causes an extension AL. Model the material as a cubic lattice, where the atoms lie at the corners of the cubes and are connected by springs with equilibrium length x. Calculate the force constant k of the atomic springs by deriving expressions for (1) the number of atoms in any cross-sectional area, (2) the number of atoms in a single chain of length L, (3) the microscopic extension Ax between atoms, (4) the tensile force f between atoms, (5) write f = kAr and show that k = Yr, (6) calculate the value of k for a typical metal such as aluminum, for which Y = 70 GN/m² and x = 0.4 nm.
14) A block of mass 0.20 kg is against a spring compressed 0.20 m with spring constant 70 N/m. When the spring is released, the block moves along the frictionless surface until entering a region with a coefficient of kinetic friction equal to 0.36 (when the block enters the friction region it is no longer in contact with the spring). How far, L, into the region with friction does the block slide before stopping? k = 70 N/m 0.36 Ax 0.20 m m = 0.20 kg Initial frictionless Ax Final ell frictionless L
11 of 24 > Constants Periodic Table A block of mass m is placed in a smooth-bored spring gun at the bottom of the incline so that it compresses the spring by an amount c. The spring has spring constant k. The incline makes an angle 0 with the horizontal and the coefficient of kinetic friction between the block and the incline is u. The block is released, exits the muzzle of the gun, and slides up an incline a total distance L. (Figure 1) Part A Find L, the distance traveled along the incline by the block after it exits the gun. Ignore friction when the block is inside the gun. Also, assume that the uncompressed spring is just at the top of the gun (i.e., the block moves a distance rc while inside of the gun). Use g for the magnitude of acceleration due to gravity. Express the distance L in terms of xc, k, m, g, µ, and 0. • View Available Hint(s) ? L = Submit Provide Feedback Next > Figure < 1 of 1 m

Calculating Thermal StressConcrete blocks are laid out next to each other on a highway without any space between them, so they cannot expand. The construction crew did the work on a winter day when the temperature was 5 °C . Find the stress in the blocks on a hot summer day when the temperature is 38 °C . The compressive Young’s modulus of concrete is Y = 20 × 109 N/m2 .StrategyAccording to the chapter on static equilibrium and elasticity, the stress F/A is given by FA = Y ΔLL0, where Y is the Young’s modulus of the material—concrete, in this case. In thermal expansion, ΔL = αL0 ΔT.We combine these two equations by noting that the two ΔL’s are equal, as stated above. Because we are not given L0 or A, we can obtain a numerical answer only if they both cancel out.
