Answer:
B
Explanation:
Keep only what is used. Remove all unnecessary items. Red tag these items for review.
Answer:
3
Explanation:
Bending stress = 117 MPa
Yield stress = 354 MPa
Factor of safety is defined as the ratio of yield stress to the allowable stress (tensile, compressive or bending) of a given material
So, factor of safety is almost equal to 3.
Answer:
Resistance = 3 Ω
Explanation:
As we know that, By Ohm's Law
V = IR
where
V is the voltage in volt
I is the current in amps
R is the resistance in ohm
Now,
Given that,
V = 15 volts
I = 5 amps
So,
R = V/I
= 15/5
= 3 Ω
⇒R = 3 Ω
