What are the 3 types of thermal energy transfer? Heat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact. Convection is the movement of heat by a fluid such as water or air. Radiation is the transfer […]

What happens when a material is deformed Why?
What happens when a material is deformed Why? When a sufficient load is applied to a metal or other structural material, it will cause the material to change shape. This change in shape is called deformation. A temporary shape change that is self-reversing after the force is removed, so that the object returns to its […]

What is the difference between an active and a passive wheel speed sensor?
What is the difference between an active and a passive wheel speed sensor? Passive sensors are larger and less accurate than active sensors and only start to operate when the wheel reaches a certain speed, therefore they have limited operation at lower speed. Active sensors require an external power source to operate and work in […]
