What are the two classification of materials? All the elements are broadly divided into metals and non-metals according to their properties. alloy. Metallic materials possess specific properties like plasticity and strength. What are the materials required for construction? Construction Material Quantity Estimation for 1000 sq. ft of House Construction Cement bags. Cement bags are required […]
Do resistors have voltage ratings?
Do resistors have voltage ratings? The power rating and voltage rating of a resistor are one common source of confusion. This far exceeds the power rating of the part. Conversely, for high resistance values, the amount of electrical energy that the 0603 resistor can withstand is determined by the working voltage rating of 75 volts. […]

Which factors determine whether a fluid flow is laminar or turbulent?
Which factors determine whether a fluid flow is laminar or turbulent? Laminar flow occurs at lower velocities, below a threshold at which the flow becomes turbulent. The velocity is determined by a dimensionless parameter characterizing the flow called the Reynolds number, which also depends on the viscosity and density of the fluid and dimensions of […]
How can we catch all kind of exceptions in a single catch block?
What is the diameter of the impression?
What is the diameter of the impression? The diameter of the impression is the average of two readings at right angles and the use of a Brinell hardness number table can simplify the determination of the Brinell hardness. How can a microscope help us study living things? A microscope allows scientists to view detailed relationships […]
How do you calculate helium balloon lift?
What is plant machinery and equipment?
What is plant machinery and equipment? The term ‘plant’ refers to machinery, equipment and apparatus used for an industrial activity. Very broadly, ‘tools’ might be considered to be instruments that are used by hand, whereas ‘equipment’ might refer to a set of tools used for a single purpose. What precautions should you take around machinery? […]
How do you calculate specific gravity from specific weight?
How do you calculate specific gravity from specific weight? Multiply the density by the acceleration of gravity (9.81) to calculate the specific weight. In our example, the specific weight is 840 x 9.81 = 8,240.4. Measure or obtain elsewhere the volume of the substance. Convert the volume to the cubic meter unit. What is the […]
Why Uranium 238 is not fissile?
Why Uranium 238 is not fissile? By contrast, the binding energy released by uranium-238 absorbing a thermal neutron is less than the critical energy, so the neutron must possess additional energy for fission to be possible. Consequently, uranium-238 is a fissionable material but not a fissile material. Is uranium 238 fissile? Unlike uranium-235, it is […]
