How do you measure viscosity using a viscometer?
How do you measure viscosity using a viscometer? BACKGROUND Ostwald viscometer is use to determine viscosity of Newtonian fluid. η1 can be determine using following equation. η1=ʆ1t1/ ʆ2t2 X η2 ʆ1=Density of unknown liquid. t1 =Time of flow of unknown liquid. ʆ2 =Density of standard liquid. t2 =Time of flow of standard liquid. η2=Viscosity of […]
What is non minimum phase transfer function?
What is non minimum phase transfer function? Systems that are causal and stable whose inverses are causal and unstable are known as non-minimum-phase systems. A given non-minimum phase system will have a greater phase contribution than the minimum-phase system with the equivalent magnitude response. What is the definition of a zero in a transfer function? […]
What is a real world math problem?
What is a real world math problem? A mathematical problem is a problem that is amenable to being represented, analyzed, and possibly solved, with the methods of mathematics. This can be a real-world problem, such as computing the orbits of the planets in the solar system, or a problem of a more abstract nature, such […]
What is rapid prototyping and what are its benefits?
What is rapid prototyping and what are its benefits? Rapid prototyping provides engineer, design and development teams with distinct advantage such as: The ability to explore and realize concepts more quickly. This efficiency in time and cost allows teams to move beyond the mere visualization of a product, making it easier to grasp the properties […]
What is negative springback?
What is negative springback? This phenomenon is called springback. Also, under certain conditions, the final bending angle may be smaller than the original angle. Such a bend- ing angle is referred to as negative springback [1]. Why is it necessary to Overbend material during a bending operation? When bending a piece of sheet metal, the […]
Why does air go from high pressure to low pressure?
Why does air go from high pressure to low pressure? Energy from the Sun As the atmosphere heats, the warmer air rises which creates areas of lower pressure. The colder, denser air forming adjacent high pressure systems moves to fill in the space left by the rising warmer air. What causes high and low pressure […]
What is the formula for shear strain?
What is the formula for shear strain? shear strain = Δ x L 0 . shear stress=F∥A. shear stress = F ∥ A . The shear modulus is the proportionality constant in (Figure) and is defined by the ratio of stress to strain. How do you calculate shear strain in torsion? Mechanical properties of materials: […]
How do you perform a hardness test?
How do you perform a hardness test? A hardness test is typically performed by pressing a specifically dimensioned and loaded object (indenter) into the surface of the material you are testing. The hardness is determined by measuring the depth of indenter penetration or by measuring the size of the impression left by an indenter. How […]
What do solenoids and electromagnets have in common?
What do solenoids and electromagnets have in common? Both solenoids and electromagnets use electric current and coiled wires to produce strong magnetic fields. Solenoids – by running current through a wire which is wound into many loops, you strengthen the magnetic field in the center of the coil. A coil of wire with a current […]
