What is the value of resistance R? R=I2100=100Ω What is the formula of resistance R? Given this, we now have two known quantities for use in our calculation – the voltage and the current. Using the Ohms law triangle, the required resistance is calculated from the formula “R=V/I”, which gives us 12/0.015=800 Ohms (see below […]

Is Per toxic? Polymer Environmental Resin (PER) The yoga mat that prompted this post is made from a material called “PER.” This mat has been Oeko-Tex 100 Tested and Approved and are Safe, Non Toxic, Hypoallergenic, No Phthalates, Phenols or PAHS, Free from Latex, Rubber or Silicone. Is TPE eco friendly? TPE is an eco-friendly […]

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 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 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 […]

What is the resolution of 8-bit ADC? An ADC generates a digital output that’s proportional to the ratio of the input voltage to the input range. The resolution (Δ or least significant bit) is this range divided by the total number of possible steps. For example, an 8-bit ADC with a 2.048-V input range has […]

How do you calculate gearbox torque? The torque is calculated as follows: Obtain load F of the meshing point (at the radius of the pitch circle of Gear A) of the input torque. Obtain torque of the output side from load F of the teeth’s meshing point (radius of the pitch circle of Gear B). […]

What do you call the machine that cuts off heads? A guillotine (/ˈɡɪlətiːn/ GHIL-ə-teen, also US: /ˈɡiːətiːn/ GHEE-, French: [ɡijɔtin] ( listen)) is an apparatus designed for efficiently carrying out executions by beheading. The device consists of a tall, upright frame with a weighted and angled blade suspended at the top. What is a guillotine […]

What object has a net force of zero acting on it? The net force is the vector sum of all the forces acting on an object. When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero. A vector can only have zero magnitude if […]

What is reheating in Rankine Cycle? Reheating is a method of improving Rankine cycle efficiency which consists of inter-stage heating of the expanding steam. After the first stage of expansion which typically reduces initial steam pressure by one-fourth, the steam is heated up (or close) to the maximum heat source temperature. What is regeneration in […]
