Answer: (b) temperature and torsional effects are automatically compensated for by the bridge,
Explanation:
As can be seen, strain gages 1 and 4 are on top of the beam and strain gages 2 and 3 are on the bottom of
the beam. Therefore strain gages 1 and 4 experience a tensile strain (are stretched) and strain gages 2
and 3 experience a compressive strain. If the relationship between strain and resistance is linear, then
under some load F the changes in resistance will be
R1= R1 + dR1
R4= R4 + dR4
tensile(4)and
R ¢2= R2 -dR2
R ¢3= R3 -dR3
compressive. (5)
when the four strain gages have an equal nominal
resistance (i.e., R1 = R2 = R3 = R4 = R) then the deflection method Wheatstone bridge equation reduces to the linear equation
Using known weights, a calibration curve can be established that relates the weight W to the output
voltage on a digital meter Eo,
Eo= a0 + a1W , (4)
where a0 and a1 are some constants. Once an unknown weight is known, an unknown mass or density
Amplitude: the height of the wave
wavelenght: the distance betweeen adjacent crests
period: the time it takes for one complete wave to pass a given point
Ik what it is hit me up for it
Explanation:
It is given that,
Initially, the jogger is at rest u₁ = 0
He accelerates from rest to 4.86 m, v₁ = 4.86 m
Time, t₁ = 2.43 s
A car accelerates from u₂ = 20.6 to v₂ = 32.7 m/s in t₂ = 2.43 s
(a) Acceleration of the jogger :


a₁ = 2 m/s²
(b) Acceleration of the car,


a₂ = 4.97 m/s²
(c) Distance covered by the car,


d₁ = 5.904 m
Distance covered by the jogger,


d₂ = 64.73 m
The car further travel a distance of, d = 64.73 m - 5.904 m = 58.826 m
Hence, this is the required solution.
Answer:
products would appear after the raw materials
Explanation:
raw material + raw material = product (anything deriving from combining two materials)
