What is the step in the design process where you identify a problem or need that exists? The steps: The steps: ask to identify the need and constraints, research the problem, imagine possible solutions, plan by selecting the most promising solution, create a prototype, test and evaluate the prototype, and improve and redesign as needed. […]
How piezoelectric transducer can be used for pressure measurement?
How piezoelectric transducer can be used for pressure measurement? When a force is applied to a piezoelectric material, an electric charge is generated across the faces of the crystal. This can be measured as a voltage proportional to the pressure (see diagram to the right). As a result, piezoelectric sensors are not normally suitable for […]
How does gravity affect a car?
How does gravity affect a car? Gravity has a major effect on your vehicle when you are driving downhill or uphill. When you are driving uphill, gravity’s power is working against you, meaning it pulls your car the opposite direction, which slows down your car. You will need more engine power in order to stay […]
Why are metals conductive and polymers not conductive?
Why are metals conductive and polymers not conductive? Why are metals better conductors than polymers? These electrons are known as delocalised and so are ‘free to move’ across the surface of the metal. These free movement of electrons allows electricity to pass across a metal. In polymers, no such situation arrises and so electricity cannot […]
What is km in Lineweaver-Burk plot?
What is km in Lineweaver-Burk plot? The y-intercept of the Lineweaver- Burk plot is the reciprocal of maximum velocity. KM: Michaelis-Menten constant or enzyme affinity. The lower the KM the higher the affinity. Graphically the x-intercept of the line is -1/KM. Kcat: turnover number, or reactions per unit time. What happens when there is a […]
What affects the severity of an electric shock?
What affects the severity of an electric shock? The three primary factors affect the injury severity of an electric shock: 1) the amount of current passing through the body 2) the duration of the current flow and 3) the current path through the body. What are four factors that affect the severity of an electrical […]

What is the glass transition temperature of a polymer?
What is the glass transition temperature of a polymer? The glass transition temperature is the temperature range where the polymer substrate changes from a rigid glassy material to a soft (not melted) material, and is usually measured in terms of the stiffness, or modulus. What happens to a polymer that is heated to the glass […]
