How does an ABS speed sensor work? The sensors work with the toothed tone wheels to monitor and provide the anti-lock brake module (ABM) with wheel speed information. The result is an alternating current (AC) voltage that is generated in the speed sensor coil by magnetic lines of force fluctuating as the tone wheel passes […]

How do you calculate nominal interest compounded monthly? For example: assume you deposit 100 dollars in a bank account and the bank pays you 6% interest compounded monthly. This means the nominal annual interest rate is 6%, interest is compounded each month (12 times per year) with the rate of 6/12 = 0.005 per month, […]

How do you calculate the temperature of a heat exchanger outlet? The main basic Heat Exchanger equation is: Q = U x A x ΔTm = The log mean temperature difference ΔTm is: ΔTm = (T1 – t2) – (T2 – t1) = °F. Where: T1 = Inlet tube side fluid temperature; t2 = Outlet […]

What is a 1 point perspective? One point perspective is a type of drawing created on a 2D plane that uses one point in the distance from which everything in the drawing is set out. What is 1 point and 2 point perspective? In one-point perspective, all lines converge to a single point on the […]

What three things drive a roller coaster? Roller coasters rely on gravity to take them to the end of the track. This involves two types of energy, potential energy and kinetic energy. Who invented roller coasters? LaMarcus Thompson What makes a good roller coaster? A great roller coaster has what one would call good pacing. […]

How do you play Rock Paper Scissors with more than 2 people? If you want to play Rock Paper Scissors with a group of 2 or more people it is very simple, everyone in the group plays a gesture and if all 3 gestures are showing everyone plays again. If only 2 gestures are showing […]

Support shall comply with Table 352.30, based on the size of the conduit. Shall be secured and fastened within 3 feet of a box, conduit body, or other point […]

What are the two types of battery charging methods? What are the two main methods used to charge batteries? The two main methods used to charge batteries are constant current charging and constant voltage charging. The method used depends on the characteristics of the battery. What are the different types of battery chargers? Type Simple […]

Does SPI have one master? SPI devices communicate in full duplex mode using a master-slave architecture with a single master. The master device originates the frame for reading and writing. Multiple slave-devices are supported through selection with individual slave select (SS), sometimes called chip select (CS), lines. Can I2C have multiple masters? The I2C component […]

What is ferritic and austenitic steel? Ferritic stainless steels are magnetic, while austenitic stainless steels in the annealed condition are not. When the austenite converts to martensite, strength increases, ductility increases, and the structure becomes magnetic. What is ferrite stabilizer? The ferrite stabilizers are chromium, silicon, molyb- denum and columbium. It is the balance between […]
