How do you identify process improvements? 4 Steps for an Effective Business Process Improvement Cycle Identify the need for change: The first step in the BPI process is to identify the need for change. Analyze current process: Once you have decided which process you are going to improve you need analyze the current procedure. Obtain […]

What does the stator do in an alternator? The stator is fixed to the shell of the alternator, and does not turn. As the rotor turns within the stator windings, the magnetic field of the rotor sweeps through the stator windings, producing an electrical current in the windings. Because of the rotation of the rotor, […]

What are the strokes of a 4 stroke cycle? An internal-combustion engine goes through four strokes: intake, compression, combustion (power), and exhaust. How many of the 4 strokes turn the engine? 2 How many times for every 4 strokes in a 4 stroke engine cycle does the crankshaft rotate? A 4-stroke engine fires once every […]

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 […]

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 […]

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. […]
