Answer:
The Purpose of Refrigeration. The fundamental reason for having a refrigerator is to keep food cold. Cold temperatures help food stay fresh longer. The basic idea behind refrigeration is to slow down the activity of bacteria (which all food contains) so that it takes longer for the bacteria to spoil the food.
Explanation:
Answer:
The cold temperature does not allow breeding of bacteria that can contaminate food

How could the location of tests affect the performance of a catapult ?
Answer:
It could affect how far the projectile travels
Explanation:
Facing Uphill: Moves less far
Downhill: Moves further
The location of tests affect the performance of a catapult depending on the length of the arm.
Explanation:
A ball from a catapult, will travel a longer distance by increasing the length of the arm. Using the catapult, if the arm is extended to different lengths the wooden ball how far it is thrown can be observed.
This shows that extending the arm length does increase the distance thrown. To shoot a far distance (example for sideways) you need to the pebble sideways and up. By doing this, it can travel a longer distance
True or False:A retractable service pit cover can help other shop employees from falling into the pit while another technician is in the pit servicing a car
A retractable service pit cover can help other shop employees from falling into the pit while another technician is in the pit servicing a car? The given statement is true statement.

A single light window is designated 16 R UP . each riser is 6” high . What is the total rise of the stairs
Answer:
96" or 96" / 12" = 8'
Explanation:
16 R UP means 16 risers up so 16 * 6" = 96" or 96" / 12" = 8'
The bar has a length L and cross-sectional area A. Determine its elongation
due to the force P and its own weight. The material has a specific weight y
(weight/volume) and a modulus of elasticity E.
Answer:
(2PL + yAL²) / (2EA)
Explanation:
For any position x along the bar measured from the top, the stress is:
σ = F(x) / A
where F(x) is the force at position x,
and A is the cross sectional area.
The stress also equals:
σ = E ε(x)
σ = E dδ / dx
where E is the modulus of elasticity,
dx is a short length of bar,
and dδ is the deflection of that short length.
Therefore:
E dδ / dx = F(x) / A
E dδ / dx = (P + yAx) / A
dδ = 1/(EA) (P + yAx) dx
The total deflection is:
δ = ∫ dδ
δ = ∫₀ᴸ 1/(EA) (P + yAx) dx
δ = 1/(EA) ∫₀ᴸ (P + yAx) dx
δ = 1/(EA) (Px + ½yAx²) |₀ᴸ
δ = 1/(EA) (PL + ½yAL²)
δ = (2PL + yAL²) / (2EA)
Oil is graded by the
A. Society of Automotive Teachers
B. Society of Automotive Engineers
C. League of Automotive Gurus
D. Bureau of Automotive Technicians
Answer:
Oil is graded by the Society of Automotive Engineers - B.
Answer:
correct option is B. Society of Automotive Engineers
Explanation:
solution
we know that Oil is graded by (SAE) Society of Automotive Engineers
because Society of Automotive Engineers is providing rating for automobile horsepower by the long time period
and Previously standard heat is Society of Automotive Engineers gross power
but it is unable to give realistic measurement per rating of the performance
after that they change their standard for more intact and start Society of Automotive Engineers
that is give very compact rating of performance
so correct option is B. Society of Automotive Engineers
Determine the maximum mass of the crate so
that the tension developed in any cable does
not exceeded 8.6 kN. (Figure 1)
Express your answer to three significant
figures and include the
appropriate units.
Answer:
293 kg
Explanation:
Let's say the tension in each cable is Tb, Tc, and Td.
First, find the length of cable AD:
r = √(2² + 2² + 1²)
r = 3
Using similar triangles:
Tdx = 2/3 Td
Tdy = 2/3 Td
Tdz = 1/3 Td
Sum of the forces in the x direction:
∑F = ma
Tb − 2/3 Td = 0
Td = 3/2 Tb
Sum of the forces in the y direction:
∑F = ma
2/3 Td − Tc = 0
Td = 3/2 Tc
Sum of the forces in the z direction:
∑F = ma
1/3 Td − mg = 0
Td = 3mg
From the first two equations, we know Td is greater than Tb or Tc. So we need to set Td to 8.6 kN, or 8600 N.
8600 N = 3mg
m = 8600 N / (3 × 9.8 m/s²)
m ≈ 292.5 kg
Rounded to three significant figures, the maximum mass of the crate is 293 kg.

Answer:
In linear systems is the principle that a response Rab, measured at a location (and direction if applicable). A, when the system has an excitation signal applied at a location (and direction if applicable), B, is exactly equal to Rba which is the response at location b, when that same excitation is applied at a. This applies for all frequencies of the excitation signal.
