How do you set a range on a multimeter? You have to set the multimeter to a range that it can measure. For example, 2V measures voltages up to 2 volts, and 20V measures voltages up to 20 volts. So if you’ve measuring a 12V battery, use the 20V setting. What does the range button […]
How is the change in entropy affected by temperature?
How is the change in entropy affected by temperature? Affecting Entropy If you increase temperature, you increase entropy. (1) More energy put into a system excites the molecules and the amount of random activity. (2) As a gas expands in a system, entropy increases. (4) When a liquid becomes a gas, its entropy increases. What […]
Is it possible for two screw dislocations of same sign to annihilate each other explain your answer?
Is it possible for two screw dislocations of same sign to annihilate each other explain your answer? It is possible for two screw dislocations of opposite sign to annihilate one another if their dislocation lines are parallel. What is the difference between the angle of Burgers vector and dislocation line in edge dislocation? Explanation: The […]
Which of the following assumptions is wrong for truss analysis?
Which of the following assumptions is wrong for truss analysis? Any loads that act between joints are split into equivalent support end reactions and added to the joint loads. Self weight of the truss can be ignored or at least assumed to be equally distributed as loads at the joints. Even if the members are […]
Why is it important for an engineer who is designing a new home cooling heating system to have knowledge about the transfer of heat?
Why is it important for an engineer who is designing a new home cooling heating system to have knowledge about the transfer of heat? Heat gradient is important for heat transfer between systems because heat travels from the warmer system to the cooler system. The right medium for heat transfer is also important for this […]
What causes thermal energy transfer?
What causes thermal energy transfer? Thermal energy is transferred from hot places to cold places by convection. As the hot air above a radiator rises it pushes cooler air away from it. The cooler air eventually circulates back round to the radiator where it gets heated and the cycle continues. What is boundary condition in […]
How can a motorist reduce the chance of a crash?
How can a motorist reduce the chance of a crash? A motorist can reduce the chances of a collision by knowing and using the standard collision – prevention formula, what is this formula? Explain what each means. Be alert: Never think the other motorist will not make a driving mistake. What is the standard collision […]
What controls the direction of motion of actuator?
What controls the direction of motion of actuator? In simple terms, it is a “mover”. An actuator requires a control signal and a source of energy. The control signal is relatively low energy and may be electric voltage or current, pneumatic, or hydraulic fluid pressure, or even human power. Which of the following components are […]
What is the rate of customer demand called?
What is the rate of customer demand called? Takt time Which of these is the best definition of takt time? Takt time is the rate at which you need to complete a product in order to meet customer demand. It comes from the German word “Takt,” meaning beat or pulse in music. Within manufacturing, takt […]
How is soil permeability measured?
How is soil permeability measured? Soil permeability, also termed hydraulic conductivity, is measured using several methods that include constant and falling head laboratory tests on intact or reconstituted specimens. Alternatively, permeability may be measured in the field using insitu borehole permeability testing (e.g. [2]), and field pumping tests. How many test in the lab can […]
