Answer:
Gypsum
Explanation:
Gypsum is the mineral group that is most important for the production of drywall used in residential home construction. Drywall, also known as gypsum board or gypsum wallboard, is made from gypsum plaster that is sandwiched between two sheets of heavy paper or fiberglass matting. The gypsum plaster used in drywall is derived from gypsum rock, which is a mineral group composed of calcium sulfate dihydrate. Gypsum is a readily available and inexpensive material that is well-suited for use in drywall due to its fire-resistant properties, ease of handling and cutting, and ability to be molded into various shapes and sizes.
calculate the total deformation in a 25ft long, 4 in. diameter steel bar hanger that supports a 390 kip load. this bar is also subjected to a change in temperature from 140of before loading to -10of after loading, calculate the change in length due to temperature change. (esteel
The variation in length caused by temperature, according to the supplied statement, is 0.2925 inch.
How would you define the deformation?A alteration in shape put through the application of pressure is referred to as deformation. It is understood that even very small stresses can cause some deformation. When an outside load applied on an item, deformation happens. Crumpling, twisting, pulling, or tearing the object apart may be required to accomplish this.
Length = 25ft = 300 inch
Diameter = 4 inch
Load (P) = 390 kips = 390000lb
Initial temperature = 140°F
Final Temperature = -10°F
ΔT Change in temperature = -10 - 140 = -150°F
Modulus of elasticity E (steel) = 30 * 10⁶ psi
Coefficient of thermal expansion = 0.0000065inch/F°
Change in length due to temperature
= L * ΔT = 300 * 0.0000065 * 150
Change in length = 0.2925 inch

What is the 2nd intermediate frequency on the receiver side of a yaesu ft-70dr?
In double-conversion superheterodyne receivers, a first intermediate frequency of 10.7 MHz is often used, followed by a second intermediate frequency of 470 kHz .
What is the 2nd intermediate frequency?
The intermediate frequency range is not a clearly defined frequency range; it lies between the low frequency (Low frequency (0.1 Hz–1 kHz)) and the radiofrequency (Radio frequency (10 MHz–300 GHz)).The popular RTL-SDR, a USB stick actually produced for DVB-T reception, also uses this technology with the E4000 as DSP, while the R820T is the next variant with an intermediate frequency of 3.57 or 4.57 MHz.The audio spectrum is the audible frequency range at which humans can hear and spans from 20 Hz to 20,000 Hz.

Explanation:
coefficient of linear expansivity of Aluminum, = 25 x 10⁻⁶ ⁰C⁻¹
coefficient of linear expansivity of steel, = 12 x 10⁻⁶ ⁰C⁻¹
Change in length of aluminum; ΔL = **ΔT
Change in length of steel; ΔL = **ΔT
difference in length of Aluminum and steel;
- = 0.55 m, for this difference to remain constant, then ΔL = ΔL
From the equation above, = 0.55 +
Since, ΔL = ΔL, then **ΔT = **ΔT
At constant temperature, the equation becomes;
