Which sensor is used for measuring acceleration and tilt? Accelerometers Is used for measuring acceleration and tilt? Accelerometers measure acceleration. That is acceleration due to movement and also acceleration due to gravity. Accelerometers are often used to calculate a tilt angle. What is the output of accelerometer sensor? Accelerometers typically fall into two categories – […]

Why is copper more conductive than aluminum?
Why is copper more conductive than aluminum? Copper has a significantly lower specific electrical resistivity than aluminium: 100, compared to 160. To attribute to an aluminium conductor the same resistance as a copper conductor, the cross-sectional area of the aluminium conductor must become larger to compensate for aluminium’s higher electrical resistivity. Is copper more conductive […]
What is grain in steel?
What is grain in steel? Grain, in metallurgy, any of the crystallites (small crystals or grains) of varying, randomly distributed, small sizes that compose a solid metal. Randomly oriented, the grains contact each other at surfaces called grain boundaries. What is the process in steel to refine the grain structure? Grain refinement can be achieved […]
How are tolerances shown on an engineering drawing?
How are tolerances shown on an engineering drawing? Tolerance is the total amount a dimension may vary and is the difference between the maximum and minimum limits. Tolerances are represented as Tolerance Values (A) or as Direct Limits (B). Nominal Size is used to describe the general size of a part. Actual Size is the […]
Which of the following welding process processes uses a non consumable electrode during welding?
Which of the following welding process processes uses a non consumable electrode during welding? Gas tungsten arc welding What is the purpose of the non consumable in TIG welding? As we said before, the electrode used in TIG welding is non-consumable, which means the filler metal application step and the heating step are separate, allowing […]
What would happen if the electric heating element in a kettle was placed at the top of a kettle?
What factors affect polymer properties?
What factors affect polymer properties? Numerous factors affect various mechanical properties of polymers, in- cluding molecular weight, processing, extent and distribution of crystallinity, composition of polymer, and use temperature. What is additives in polymer? Additives are chemicals added to the base polymer to improve processability, prolong the life span, and/or achieve the desired physical or […]
What is principal shear stress?
What is principal shear stress? Principal Stress: Maximum and minimum normal stress possible for a specific point on a structural element. Shear stress is 0 at the orientation where principal stresses occur. Principal Angle: The angle of orientation at which principal stresses occur for a specific point. What is the difference between principal stress and […]
