How can yield strength be reduced?
How can yield strength be reduced? For the majority of materials, the yield strength decreases with increasing temperature. In metals, this decrease in yield strength is due to the thermal activation of dislocation motion, resulting in easier plastic deformation at higher temperatures. What happens when plastic is cooled? Once a plastic has been cooled below […]
What is the movement of the surface of the water?
What is the movement of the surface of the water? Surface movement includes rivers, streams, creeks, lakes, ponds, and human-made “flood” control. All surface water is trying to reach sea level due to gravity. As water flows in channels, the streambed and banks of the channel will resist the flow of water. Who has the […]

When we touch a metal spoon it feels cold Why?
When we touch a metal spoon it feels cold Why? A: In general, metals feel colder or hotter to the touch than other materials at the same temperature because they’re good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects. How do you feel when you touch […]
Why is it called Organ of Corti?
What is the best wood flooring to use over radiant heat?
What is the best wood flooring to use over radiant heat? One of the best options over radiant heat is to use an engineered hardwood floor. The inherent dimensional stability of engineered hardwood floors makes it a great choice for radiant heat systems. Certain solid hardwood floors are appropriate as well. Can you put rugs […]
What are the 3 types of range of motion?
What are the 3 types of range of motion? Range of motion exercises There are three types of ROM exercises: passive, active, and active assists. Why full range of motion is important? Using a full range of motion when exercising is very important for developing and maintaining good flexibility. In addition, a full range of […]
Which hormone is responsible for sweating?
Which hormone is responsible for sweating? Acetylcholine acts on the eccrine glands and adrenaline acts on both eccrine and apocrine glands to produce sweat. Emotional sweating can occur anywhere, though it is most evident on the palms, soles of the feet, and axillary regions. How do I unblock my sweat glands? Keep the area clean. […]
What happens to a dead star?
What happens to a dead star? Stars die because they exhaust their nuclear fuel. Once there is no fuel left, the star collapses and the outer layers explode as a ‘supernova’. What’s left over after a supernova explosion is a ‘neutron star’ – the collapsed core of the star – or, if there’s sufficient mass, […]
