What range is displayed on a high pressure gauge on a service manifold? 0 to 500 psig What color is the low pressure gauge on a typical gauge manifold set? blue What units does a compound pressure gauge for the low side of the system measure pressure in? The compound gauge measures low pressure (psig) […]

What is search in C? Linear search in C to find whether a number is present in an array. If it’s present, then at what location it occurs. It is also known as a sequential search. It is straightforward and works as follows: we compare each element with the element to search until we find […]

What is the difference between the spring type clutch and diaphragm clutch? (e) The diaphragm acts as both clamping spring and release-finger. (g) Clamping load in diaphragm-spring is independent of the engine speed whereas coil springs tend to bend along their length and loose their thrust at high speeds. (h) In this clutch disengagement pressures […]

How do you deal with low voltage? Use the next-highest setting above the battery’s voltage. Press the test leads against the battery terminals (you don’t have to match the test leads to specific terminals). A low voltage indicates that the battery is probably shot. Take the tool, battery, and charger to a service center. How […]

What is the primary duty of a machine tool operator? Machine Operator Responsibilities: Assist in the installation, maintenance, and repair of machinery. Operate tools in order to aid in the manufacturing process. Perform periodic checks on equipment and solve problems as detected. Work with others in order to ensure that equipment is in proper working […]

What is the Kelvin Planck statement of the second law? The Kelvin–Planck statement (or the Heat Engine Statement) of the second law of thermodynamics states that it is impossible to devise a cyclically operating heat engine, the effect of which is to absorb energy in the form of heat from a single thermal reservoir and […]

What is domain ferromagnetism? In ferromagnetic materials, smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. Their atomic makeup is such that smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. What is […]

How do you find the reliability of a parallel system? For example, if two components are arranged in parallel, each with reliability R 1 = R 2 = 0.9, that is, F 1 = F 2 = 0.1, the resultant probability of failure is F = 0.1 × 0.1 = 0.01. The resultant reliability is […]

What order should jumper cables be put on when jump starting a vehicle? Step 3: With both cars off and in “park,” connect the jumper cables in the following order: Connect one red clamp to the positive (+) battery post of the “dead” battery. Connect the other red clamp to the positive (+) post of […]

How do you calculate the magnetic flux density? The magnetic field vector B is defined by the force it would apply to a charge moving in it. B = F/qv, so the units are (N *s) / (C *m), which we call a Tesla, or T. This is also called flux density. Flux is then […]
