How do you find the angle of twist? Angle of twist T is the internal torque (Nm), L is the length of segment (m), J is the polar moment of inertia (m4) and G is the shear modulus (GPa). Answer obtained is in radians (rad), but we usually convert it to degrees. How is angle […]

What is hypothesis and examples? Usually, you don’t want to state a hypothesis as a question. You believe in something, and you’re seeking to prove it. For example: If I raise the temperature of a cup of water, then the amount of sugar that can be dissolved in it will be increased. What is a […]

Which of the following is a characteristic of urban sprawl? Urban Sprawl is generally characterized by discontinuous, haphazard, uncoordinated, unplanned or poorly planned urban development. It is characterized by low density, excessive consumption of land, automobile dependence, separation of land-uses, social segregation and displeasing aesthetics. What are the benefits of urban sprawl? Thanks to less […]

What are the 3 types of lighting? 3 Basic Types of Lighting Ambient lighting. Task lighting. Accent lighting. What is the best type of lighting? LED bulbs fit standard light sockets and are the most energy-efficient option. LEDs have lower wattage than incandescent bulbs but emit the same light output. This allows them to produce […]

How does temperature affect conductivity of semiconductors? As the temperature increases, more electrons get the energy to jump from Conduction band to valence band, and thereby increases the conductivity of the semiconductor. How does temperature affect electrical conductivity of metals? When temperature increases, the thermal speed of the electrons increases as well as, the amplitude […]

Do 2-cycle engines need oil gas? Two-stroke (two-cycle) engines require you to mix the oil with the gas in exact amounts so the oil acts as a lubricant for the crankcase, while four-stroke engines take oil and gas separately. In a 2-stroke engine, it takes one full revolution (2 stages) to complete 1 power stroke. […]

How do you change the resistance of a resistor? Sometimes you need a resistor with a value you don’t have in your kit. Instead of ordering and wanting for a resistor with a value you need you can change the resistance of a resistor by using another resistor or many. By installing resistors in a […]

What is the importance of instrumentation in industries? Instrumentation is the basic process control in industry. In industrial control a wide number of variables temperature, flow, level, pressure, and distance can be sensed simultaneously. All of these can be interdependent variables in a single processing require a complex microprocessor system for total control. What is […]

How many atoms are in a FCC 111 plane? 2 atoms How do you calculate planar density? As an example, the area of a (1 1 0) plane of an FCC crystal is 8_sqrt(2)_R^2 where “R” is the radius of an atom within the plane. Calculate planar density with the formula: PD = Number of […]

What are the factors affecting the intensity of rivalry in the industry in which your company is competing? A number of structural factors can affect industry rivalry: Numerous or equally balanced competitors. Slow industry growth. High fixed or storage costs. Lack of differentiation or switching costs. Capacity increased in large increments. Diverse competitors. High strategic […]
