Parallel Resistor Equation
If the two resistances or impedances in parallel are equal and of the same value, then the total or equivalent resistance, RT is equal to half the value of one resistor. That is equal to R/2 and for three equal resistors in parallel, R/3, etc.
Answer:
1/2 or 1:2
Explanation:
first convert speed of compressor to rpms
Compressor speed= w1 = 150 cycles/s= 150 * 60= 9000 rpms
Speed of turbine= w2 = 18000 rpms
gear ratio = N2/N1 = w1/w2
gear ratio = 9000/18000
gear ratio = 1/2
gear ratio = 1:2
Answer:
c) Young's modulus Toughness.
Explanation:
The charpy impact test is well known in the Engineering field specifically in stress, strain and mechanical of fracture.
A theoretical definition is that the test determines the amount of energy absorbed by a material during fracture.
