Answer:
shaft is not transform 100% power
Explanation:
given data
current = 10 amp
voltage = 110 v
torque = 10.2 Nm
rotating speed N = 1000 rpm
solution
we get here first power that is consume by motor is express as
power = current × voltage .........1
power = 10 × 110
power = 1100 W
and power that transmit by shaft is express as
power = T × ω
power = T ×
power = 10.2 ×
power = 1068.14 W
so we can say from above both power
shaft is not transform 100% power

Answer:
The biggest expectation of an engineer when he tests out a new design is that he expects the product to not fail, and all the stress and strains does not exceed the failure criteria.
Explanation:
In engineering design, failure of materials is considered, and the designed is usually designed to not reach or exceed the failure region of its stress strain relationship. This is why factor of safety is usually determined for each material, and it serves as a guideline for the designing of new designs. This factor of safety is the value, below which the material properties is able to cope with design stress and strain, and above which failure is likely to occur.

Answer:
9.60%
Explanation:
Computation for the weight fraction of graphite
First step
Computation for the mass fraction for Wa using this formula
Wa=Cg-Co/Cg-Ca
Let plug
Wa=10-3/100-0
Wa=0.97
Computation for the mass fraction for Wg using this formula
Wg=Co-Ca/Cg-Ca
Let plug in the formula
Wg=3-0/100-0
Wg=0.03
Second step is to convert the mass fraction to Volume Fraction using this formula
Volume Fraction =[Wg/Pg÷(Wa/Pa)+(Wg/Pg)]*100
Let plug in the formula
Volume =[0.03/2.3 ÷(0.97/7.9)+(0.03/2.3)]*100
Volume=[0.0130435÷0.1227848+0.0130435]*100
Volume=[0.0130435÷0.135828]*100
Volume=0.096*100
Volume=9.60%
Therefore the weight fraction of graphite will be 9.60%
