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 […]

How is Euler buckling load calculated? The Euler column formula predicts the critical buckling load of a long column with pinned ends. The Euler formula is P cr = π 2 ⋅ E ⋅ I L 2 where E is the modulus of elasticity in (force/length2), I is the moment of inertia (length4), L is […]

What strategies can you use to brainstorm for speech topics? When brainstorming for speech topics, write at the top of a fresh piece of paper: “What topic should my speech be about? ” Then, under the question, let yourself write down what comes to your mind for a pre-established period of time. Let yourself generate […]

How can I improve my lab efficiency? 8 Steps to Increase Your Lab Efficiency Eliminate waste. Empower your team. Organize your lab. Track issues. Manage information. Label your samples. Calibrate your instruments. Automate your processes. How could you improve this experiment? You can increase the validity of an experiment by controlling more variables, improving measurement […]

What is the function of controller in closed loop system? In a closed-loop system, a controller is used to compare the output of a system with the required condition and convert the error into a control action designed to reduce the error and bring the output of the system back to the desired response. What […]

How do you find the frequency response of an LTI system? −jΩm = C(Ω) − jS(Ω) = H(Ω) . , where H(Ω) is the frequency response of the LTI system. The system therefore produces an output signal that is the “3-point weighted moving average” of the input. What is the frequency response of the system […]

How do you calculate the atomic packing factor for the FCC? Calculating the atomic packing factor for a crystal is simple: for some repeating volume, calculate the volume of the atoms inside and divide by the total volume. Usually, this “repeating volume” is just the volume of the unit cell. The unit cell is defined […]

What is the importance of sketching? Sketches help to convey ideas, demonstrate functionality, visualize user flow, and illustrate anything that requires human interaction. What is the most important role in free hand drawing? The line is the most important part of free hand drawing as sketching is done by different lines. Straight lines can be […]

Why is my laser printer printing lines? Streaking is usually caused by a worn out drum unit or spent toner cartridge. Drum units are a consumable and only need to be replaced after the use of 3 or 4 toners. Not all printers use a separate toner and drum unit. When you print from your […]

Is the equivalent resistance of a parallel circuit greater than or less than any individual resistor? Connecting elements in series forces all current to pass through each element. Connecting elements in parallel permits current to pass through only one element. The equivalent resistance is larger than each individual resistance. The equivalent resistance is smaller than […]
