What does P controller do? In the proportional control algorithm, the controller output is proportional to the error signal, which is the difference between the setpoint and the process variable. In other words, the output of a proportional controller is the multiplication product of the error signal and the proportional gain. Why PID controller is […]
What is sampling in ADC?
What is sampling in ADC? The sample rate for an ADC is defined as the number of output samples available per unit time and is specified as samples per second (SPS). Two aspects of sample rate that must be considered when selecting an ADC for a particular application are the minimum sample rate and maximum […]
What is the reliability of the system?
What is the reliability of the system? What is reliability? Reliability is the probability that a system performs correctly during a specific time duration. During this correct operation: No repair is required or performed. How do you determine reliability of a system? ×Fn(t) = ΠFj(t) . Reliability is complementary to probability of failure, i.e. R(t) […]
How do construction sites store materials?
How do construction sites store materials? Storage at height – if materials are stored at height eg on top of a container, make sure necessary guard rails are in place if people could fall when stacking or collecting materials or equipment; Tidyness – keep all storage areas tidy, whether in the main compound or on […]
What is the difference between macronutrients and micronutrients?
What is the difference between macronutrients and micronutrients? Macronutrients are big picture nutrition categories, such as carbohydrates, fats, and proteins. Micronutrients are smaller nutritional categories, such as individual vitamins and minerals like calcium, zinc, and vitamin B-6. You may have heard the phrase “counting macros” at some point. What is the importance of macronutrients and […]
How do welds fail?
How do welds fail? Insufficient weld size — because of design errors or incorrect interpretation of the part design – can lead to weld failures. A weld that is too small or too short for the application can fail from tension, compression, bending or torsional loads. What are common welding defects? So below we’ll learn […]
What do they ask you to do during a driving test?
What do they ask you to do during a driving test? Some of the required maneuvers include: Following other traffic. Starting your vehicle. Merging to traffic. Backing up. Parallel parking. Making a U-turn. Pulling over to the side of the road and stopping. Moving away from a parked position onto the road. What do I […]
How do you calculate the evaporation rate of water?
How do you calculate the evaporation rate of water? I did my own research, and according to The Engineering Toolbox,the formula for the evaporation rate of water is as follows: gh=ΘA(xs−x) gh = amount of evaporated water per hour (kg/h) Θ=(25+19v) = evaporation coefficient (kg/(m2 h)) v = velocity of air above the water surface […]
What is dry park check?
What is dry park check? A dry park test is performed with the transmission in “park” and the front wheels on the ground. After starting the engine, check for a “bump” or movement in the steering wheel as the engine starts. Binding strut support bearings or seized ball joints can cause the steering to feel […]
