The answer is false. Square means a corner is a 90 degrees. Plumb means it vertically perpendicular to the surface.
Answer:
A voltage divider is a simple series resistor circuit. It's output voltage is a fixed fraction of its input voltage. The divide-down ratio is determined by two resistors.
Answer and Explanation:
The main objective that the torsion test serves is the determination of the material behavior or the behavior of the test sample when subjected to torsional stresses or forces due to the application of moments that results in shear stress along the axis.
Plasticity is the property of elastic material and tension or shear stresses leads to plasticity in a material where these links are the weakest, that gives torsion test a major advantage over the tension test.
Torsion tests are performed on materials to deduct properties like the shear modulus of elasticity, the torsional strength, and the MOR, i.e., Modulus of Rupture.
This test can be used to obtain larger strain values of strain without any complexity as that in tension test.
This test provides a curve of shear-stress-shear strain which is more significant in determining the plasticity as compared to the curve of stress-strain in tension test.
Maximum torque for a given value of maximum stress will be 2 times higher in torsion as that of tension.
In torsion, for plastic flow, the threshold value of shear stress is achieved before the threshold value of normal stress for fracture whereas in tension the critical value of normal stress is achieved sooner than the critical shear for plastic flow.
Answer:
a) λ = 2 meters
b) λ = 1.76 meters
c)In free space: length of phasing section = 0.5 meters and in dielectric medium: length of phasing section =0.44 meter
Explanation:
Given that:
velocity factor = 0.88
operating frequency = 150 MHz = 150 × 10⁶ Hz
phasing section is a quarter-wavelength = λ/4
a) Wavelength of free space:
λ = c/f
where c is the speed of light = 3×10⁸
λ = (3×10⁸)/150 × 10⁶
λ = 2 meters.
b) Wavelength of dielectric:
Velocity of dielectric = speed of light (c) × velocity factor
Velocity of dielectric = 3×10⁸ × 0.88 = 2.64 × 10⁸ m/s
wavelength dielectric = Velocity of dielectric /f = (2.64 × 10⁸)/150 × 10⁶ =1.76
wavelength dielectric = 1.76 meters
c) length of the phasing section in meters:
l = λ/4
In free space:
l = 2/4 = 0.5 meter
In dielectric
l = 1.76/4 = 0.44 meter
