A metallic strain gauge of gage factor (GF = 2) has a resistance of 350 Ω at zero strain. The strain gauge is originally 1 m in length. Determine the resistance (in Ω) of the gauge when it is strained axially by 1 cm

357 Ω

Explanation:

The gage factor is one of the ways of measuring the strain in materials.

(Gage factor) = (fractional change in electrical resistance)/(fractional change in length)

Gage factor = 2

R₀ = 350 Ω

L₀ = 1 m

ΔR = ?

ΔL = 1 cm = 0.01 m

2 = (ΔR/350) ÷ (0.01/1)

(ΔR/350) = 2 × 0.01

ΔR = 350 × 0.02 = 7 Ω

New resistance = R₀ + ΔR = 350 + 7 = 357 Ω

Hope this Helps!!!

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

explanation:

the masses of the objects and the distance between them
