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 […]
What are the different types of combustion chamber?
What are the different types of combustion chamber? Can Type (Tubular) Cannular Type (Tubo-annular) Annular Type. Silo Type. Types of Combustion Chambers. Tubular (Can) The earliest aircraft engines made use of can (or tubular) combustors. Tubo-annular (Cannular) Individual flame tubes are uniformly spaced around an annular casing. Annular. Silo type. What are the different types […]
What is welding brazing and soldering?
What is welding brazing and soldering? Brazing joins two metals by heating and melting a filler (alloy) that bonds to the two pieces of metal and joins them. Soldering is a low-temperature analog to brazing. By the American Welding Society’s definition, soldering takes place with fillers (also known as solders) that melt at below 840°F […]
When entering a roundabout you must yield the right of way to?
When entering a roundabout you must yield the right of way to? At an intersection where there is no stop sign or traffic signal (with the exception of roundabouts), drivers must yield to vehicles coming from the right. When approaching a roundabout intersection, always yield to traffic in the circle and pedestrians in the crosswalks. […]
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 […]
What is static pressure and dynamic pressure?
What is static pressure and dynamic pressure? Static pressure is the pressure you have if the fluid isn’t moving or if you are moving with the fluid. Dynamic pressure is the pressure of a fluid that results from its motion. It is the difference between the total pressure and static pressure. What is meant by […]
