original question: Experimental measurements were taken from a physical measurement system that can be modeled as y=b xm. The experimental data pairs (x,y) were (1.000, 3.26), (2.000, 12.36), (3.000, 28.04), (4.000, 50.04), (5.000, 77.48). Find the coefficients (b, m) that fit the model using the method of least squares (and the equations provided in the lecture or textbook) and calculate the standard error of the fit. Calculate the device sensitivity. Show your answers using 3 decimal points.
All calculations were done using the given data with three decimal points.
What is decimal?
The accepted method for representing both integer as well as non-integer numbers is the decimal numeral system. It is the expansion of the Hindu-Arabic numeral system to non-integer numbers. Decimal notation is the term used to describe the method of representing numbers inside the decimal system. A decimal numeral refers generally to a notation of a number inside the decimal numeral system (also frequently just called a decimal or, less accurately, a decimal number).
The coefficients (b, m) were calculated using the method of least squares. The equation for this method is b = (n∑xy - (∑x)(∑y)) / (n∑x2 - (∑x)2) and
m = (n∑x2 - (∑x)(∑y)) / (n∑x2 - (∑x)2).
The standard error of the fit was calculated using,
The equation SE =√(∑(y-y_calc)2/ (n-2))
where y_calc is the calculated y value from the model equation.
The device sensitivity was calculated using the equation S = m/x.

Answer:
do the wam wam
Explanation:
The heat flux is =1038kW/m² , the heat lost per hour is =259.5 kW, the heat lost per hour using a sheet of soda- lime glass.
Calculation of heat fluxThe thickness of steel( t) = 10mm = 10× 10^-³m
The temperature difference on both sides = 300-100
∆T = 200°C
But the formula for heat flux = q = k∆T/t
Where K = thermal conductivity for steel = 51.9W/mK.
Substitute the variables into the formula for heat flux;
q = 51.9 × 200/10 × 10-³
q = 10380 × 10³/10
q = 10380000/10
q = 1038000 W/m² = 1038kW/m²
To calculate the heat lost per hour if the cross sectional area is = 0.25 m2 use the formula q × A
= 1038kW/m² × 0.25 m2
= 259.5 kW.

why do brittle materials fail rapidly after yield, and why do ductile materials have a period of decreasing stress after the ultimate stress?
Brittle materials fail rapidly after yield because they cannot deform plastically. Ductile materials have a period of decreasing stress after the ultimate stress because they can deform plastically.
What is brittle materials?
Brittle materials includes glass, ceramic, graphite, and some alloys with exceptionally low plasticity, in which cracks can form without plastic deformation and quickly evolve into brittle breakage. The microcutting model does not appear to be appropriate for such materials. It has been demonstrated experimentally that when a single particle meets brittle material, cracks often form at the faulty impact places when the particle impact velocity reaches a particular value, the threshold velocity.

mechanical or hydraulic devices that regulate the speed of a machine are called
Mechanical or hydraulic devices that regulate the speed of a machine are called speed governors.
Speed governors are devices used to control and maintain the desired speed of a machine or engine. They are commonly used in various applications where speed regulation is crucial, such as in engines, turbines, generators, and industrial machinery. Speed governors work by monitoring the rotational speed of the machine and adjusting the input energy to maintain a consistent speed under varying load conditions.
The main function of a speed governor is to limit or regulate the flow of energy, typically through mechanical or hydraulic means, in response to changes in the load on the machine. They achieve this by adjusting the throttle or fuel supply, controlling the flow of fluid, or changing the mechanical configuration to regulate the speed. The governor senses the speed of the machine and compares it to a set reference speed. If the actual speed deviates from the desired speed, the governor activates and modulates the energy input to restore and maintain the desired speed.
Speed governors play a crucial role in ensuring the safe and efficient operation of machines and engines. They help prevent overspeeding, which can lead to mechanical failure, overheating, or damage to the equipment. By regulating the speed, governors also contribute to maintaining stability, controlling power output, and optimizing the performance of the machine or engine in various operating conditions.
