What is most commonly a result of the tires set with excessive toe in or toe out? Among the three major alignment angles-camber, caster and toe-toe is always checked and adjusted last. Too much toe causes severe tire scuffing and may create a sawtooth or feather-edge wear pattern across the tire. Note that unlike front […]

Step 2: Remove the pushrods. Step 3: Loosen head bolts. Step 1: Remove the timing cover. Step 3: Remove the timing belt. Step 4: […]
What is static pressure measured in?
What is static pressure measured in? When measuring static pressure, the unit of measurement used is inches of water column, which is often shown as an abbreviation such as “in. wc,” “in. wg” or “in. H2O.” One key to interpreting and diagnosing static pressure is to first understand how pressures change throughout an HVAC system. […]
What is the probability of getting at least one red marble?
What is a deadlock and how can it be avoided?
What is a deadlock and how can it be avoided? In order to avoid deadlock, you have to acquire a lock in the fixed order. Once process1 commits the transaction successfully, it will release the locks on the resources; therefore process 2 will get the required resources in order to complete the transaction successfully without […]

What sparked the space race between the United States and the Soviet Union? The Space Race was a 20th-century competition between two Cold War adversaries, the Soviet Union (USSR) and the United States (US), to achieve superior spaceflight capability. It had its origins in the ballistic missile-based nuclear arms race between the two nations following […]
Which way does a capacitor discharge?
Which way does a capacitor discharge? When the capacitor is discharging, the current flows towards the negative plate, and the current flows away from the positive plate, in the opposite direction. Whereas, while the capacitor is charging, the current flows towards the positive plate and away from the negative plate. Which way round do you […]
What are the three major assumptions used in the derivation of the Bernoulli equation?
What are the three major assumptions used in the derivation of the Bernoulli equation? The flow must be steady, i.e. the fluid properties (velocity, density, etc…) at a point cannot change with time. The flow must be incompressible – even though pressure varies, the density must remain constant along a streamline. What are the assumptions […]
What are the 3 modes of heat transfer?
What are the 3 modes of heat transfer? Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation). Heat is usually transfered in a combination of these three types and seldomly occurs on its own. What type of heat transfer is air conditioning? In the HVAC and Refrigeration field, convective […]
