O backsaw
O coping saw
O hacksaw
Answer:
backsaw
Explanation:
The best designed saw for cutting miter joints is a backsaw. The correct option is 2.
What is a backsaw?Any hand saw having a stiffening rib on the edge opposite the cutting edge—known as a backsaw—enables better control and more accurate cutting than other saws.
For precise tasks like cutting dovetails, mitres, or tenons in cabinetry and joinery, backsaws are typically employed in woodworking.
Its teeth have sharp, knife-like points because they are beveled on both sides, which cuts through the fibers of the wood.
The down stroke of the crosscut saw is also used to cut. The backsaw features a small, squared-off blade that is about a foot long, and to maintain the blade straight, a sheet steel reinforcing strip is wrapped over the back of the blade.
Thus, the correct option is 2.

The predeposition heat treatment is to be conducted at 1000°C for 45 minutes, with a constant surface concentration of 8x 10^26 As atoms/m³. At a drive in temperature of 1100°C, determine the diffusion time required for a junction depth of 1.21m. For this system, values of Q and Do are 4.10 eV and 2.29x10^3m/s, respectively.
The diffusion time that is needed for the junction depth of 1.21 m is given as 13875 seconds
How to solve for the diffusion timebackground concentration of As in Si is 2.5 x 10²⁰ atoms/m
tp = 1000°c
tp = 45 minutes
= 45 x 60 seconds
surface concentration = 8x 10^26
Td = 1100°c
Junction depth = 1.2
= 1.2 x 10⁻⁶m
qd = 4.10ev
Do = 2.29 x 10⁻³
We have to use the equation
[tex]Dp = Doexp(-\frac{qd}{kTP} )\\\\= (2.23 * 10^-^1^3 m^2/s) exp [-\frac{4.10}{8.62*10^-^5 *(1000+273)} ][/tex]
= 1.36 x 10⁻¹³
From the relation that we have here
[tex]Qo = 2cs\sqrt{\frac{Dpte}{pi} } \\\\= 2 * 8* 10^2^6*\sqrt{\frac{1.36*10^-^1^3(45*60)}{pi} }[/tex]
Qo = 1.73 x 10¹³
Dd at 1100
[tex]Dd = 2.29*10^-^3exp(\frac{-4.10}{8.62x10^-^5)(1100 + 273)}[/tex]
Dd = 2.06 x 10⁻¹⁸m²/s
From the relation we have
[tex]exp[\frac{(1.2 * 10^-^6)^2}{4*(2.06x10^-^1^8)+d} ]=\frac{1.73*10^1^9}{2.5x10^2^0*\sqrt{pi*2.06*10^-^1^8x+d} }[/tex]
[tex]ln\frac{2.72*10^7}{\sqrt{+d} } =\frac{1.75*10^5}{+d}[/tex]
Using heat and trial, we would have the value of +d = 13875 seconds
The diffusion time is 13875 seconds

Which type of power system should Gavin use to create the device in the following scenario?
Gavin is designing a device that must rely on precise movements. It must have the force to cut through metal yet be safe enough for one person to hold steady on his or her own.
A. a fluid power system similar to one used in a pool pump
B. a hydraulic system similar to one used in a dump truck
C. a propulsion system similar to one used in a jet plane
D. a pneumatic power system similar to one used in a jackhammer
Given that Gavin is designing a device that must rely on precise movements. It must have the force to cut through metal yet be safe enough for one person to hold steady on his or her own. The type of power system should Gavin use to create the device in the following scenario is: " a fluid power system similar to one used in a pool pump" (Option A)
What is a Fluid Power system?A pressurized fluid bearing directly on a piston in a cylinder or in a fluid motor does work in fluid power systems. A fluid cylinder generates force, which results in linear motion, whereas a fluid motor generates torque, which results in rotating motion.
Fluid power may be utilized for exceedingly difficult work like drilling new underground mining tunnels, as well as very gentle operations like lifting and stacking enormous sheets of glass. Fluid power systems may push, pull, lift, twist, or grasp practically any load using different components and actuators.
Fluid power systems are classified into two types: hydraulic equipment, which use liquids such as water and oil, and pneumatic systems, which use neutral gases such as air.
