How do you find resistance force and effort force? In a class one lever the force of the effort (Fe) multiplied by the distance of the effort from the fulcrum (de) is equal to the force of the resistance (Fr) multiplied by the distance of the resistance from the fulcrum (dr). The effort and the […]
What is the difference between conduction and convection heat transfer?
What is the difference between conduction and convection heat transfer? Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas. Radiation is the transfer of thermal energy through thermal emission. Hope this helps! What is the difference between convection and […]
What is a table clamp called?
What is a table clamp called? Bench Clamps (aka toggle clamps) Bench clamps screw down onto work tables. This allows for quick clamping of an assembly. They are ideal for use with a wood table and can also be used with other tables through the use of attachment accessories. What are wood clamps called? The […]
What is a thin walled pressure vessel?
What is a thin walled pressure vessel? A thin-walled pressure vessel is one in which the skin of the vessel has a thickness that is much smaller than the overall size of the vessel, and the vessel is subjected to internal pressure that is much greater than the exterior air pressure. What are the assumptions […]
Can the moon crash into Earth?
Can the moon crash into Earth? The Moon will swing ever closer to Earth until it reaches a point 11,470 miles (18,470 kilometers) above our planet, a point termed the Roche limit. Theory dictates they’ll eventually rain down onto Earth’s surface. What would happen if the moon fell? If the Moon did escape from Earth, […]
What 4 elements at room temperature can become permanently magnetized?
What 4 elements at room temperature can become permanently magnetized? There are only four elements in the world that are ferromagnetic at room temperature and can become permanently magnetized: iron, nickel, cobalt and gadolinium. (A fifth element, dysprosium, becomes ferromagnetic at low temperatures.) What happens when a watch is magnetized? Magnetization is a particular problem […]
Does the sign of the acceleration alone tell you whether an object is speeding up or slowing down?
Does the sign of the acceleration alone tell you whether an object is speeding up or slowing down? Another way to say this is that if the acceleration has the same sign as the velocity, the object will be speeding up. And if the acceleration has the opposite sign as the velocity, the object will […]
How important is the lithosphere?
How important is the lithosphere? The lithosphere is largely important because it is the area that the biosphere (the living things on earth) inhabit and live upon. When the biosphere interacts with the lithosphere, organic compounds can become buried in the crust, and dug up as oil, coal or natural gas that we can use […]
What are the major components of a projectile motion?
What are the major components of a projectile motion? There are the two components of the projectile’s motion – horizontal and vertical motion. And since perpendicular components of motion are independent of each other, these two components of motion can (and must) be discussed separately. What is the vertical component of the velocity just before […]
