For what values of k is the system stable? If K < 1386, the system will remain stable. If K > 1386, the system will remain unstable. How do you determine a closed loop stability? The determination of stability is based on the closed-loop characteristic polynomial: Δ(s,K)=1+KGH(s). What are the characteristics of stable and unstable […]

What power must be in place when you first place a slide on the microscope stage? When focusing on a slide, ALWAYS start with either the 4X or 10X objective. Once you have the object in focus, then switch to the next higher power objective. Re-focus on the image and then switch to the next […]

What must be added to the polynomial f/x )= x 4 2×3 − 2×2 X − 1 so that the resulting polynomial is exactly divisible by x2 2x − 3 )? Hence, (x−2) must be added to the polynomial x4+2×3−2×2+x−1 so that the resulting polynomial is exactly divisible by x2+2x−3. What must be added to […]

How do you calculate V peak to peak? Alternating Current (AC) the peak to peak voltage = 6 squares from the highest point to the lowest and each square is worth 10V. So the peak to peak voltage = 60 V. the peak voltage ( Vo )= half the peak to peak voltage = 60 […]

What effect does the wind chill factor have on temperature? The wind chill factor describes what happens to a body when it is cold and windy outside. As wind increases, heat is carried away from the body at a faster rate, driving down both skin temperature (which can cause frostbite) and eventually the internal body […]

How do you prevent hydroplaning? How do I Avoid Hydroplaning? Keep your tires properly inflated. Rotate and replace tires when necessary. Slow down when roads are wet: the faster you drive, the harder it is for your tires to scatter the water. Stay away from puddles and standing water. Avoid driving in outer lanes where […]

What is the most common method of welding? Shielded Metal Arc Welding What are the techniques of welding? The following are the commonly used welding methods: Stick/Arc welding (SMAW) Metal Inert Gas (MIG) welding or GMAW. Tungsten Inert Gas (TIG) welding or GTAW. Flux-Cored Arc Welding. What are the common welding techniques used to different […]

What is the steady-state response of a system? A steady-state response is the behavior of a circuit after a long time when steady conditions have been reached after an external excitation. What is sinusoidal response? The sinusoidal response of a system refers to its response to a sinusoidal input: u(t)=cosω0t or u(t)=sinω0t. To characterize the […]

What metal is used for turbine blades? Nickel alloys What is the hottest part of a turbine engine? The engine exterior and the engine nacelle are cooled by passing fan air around the engine and the nacelle. The engine compartment frequently is divided into two sections. The forward section is referred to as the cold […]

What are examples of universal design? Things like curb cuts, large, color contrasting fonts, and sloped entrances are all examples of universal design. – Include Disability Services staff/students with disabilities on planning boards. What are the 7 universal design principles? The 7 Principles Principle 1: Equitable Use. Principle 2: Flexibility in Use. Principle 3: Simple […]
