Foot rule/ ruler
Explanation:
1. An Ohmmeter tests resistance of a circuit and therefore, indicates if the circuit has continuity (connectivity) by measuring the resistance to the current it sends through the circuit, while the circuit power is switched off
2. A test probe connects a testing equipment to a Device Under Test (DUT)
3. A plug is used to connect an electric appliance to the mains power supply by fitting it into the mains power outlet
4. A duplex cord is used for temporary wiring to supply power in an extension cord assembly
5. A test light is used to determine if a circuit has electric current flowing in it
6. An ammeter measures the amount of direct or alternating current flowing in a circuit
7. Test light is used to check the presence of an electric current in a circuit
8. A ruler is used to measure length and it is marked in cm or in
9. A micrometer measures the diameter of wires placed in between the anvil and spindle
10. A Volt-Ohm-Milliammeter (VOM), is also known as a multimeter that measures voltage, current, and resistance of a circuit
11. A foot rule/ ruler, measures the dimensions of objects that are flat and short
4x+2y=20 -8x-3y=16 what is y
Answer:
y = 56
Explanation:
We label each of the given equations as follows;
4·x + 2·y = 20...(1)
-8·x - 3·y = 16...(2)
Therefore, we are given a simultaneous equation, question
We make 'x' the subject of both equations and equate the result to find the value of 'y' as follows;
For equation (1)
4·x + 2·y = 20
∴ x = (20 - 2·y)/4 = 5 - y/2
x = 5 - y/2
For equation (2), we have;
-8·x - 3·y = 16
∴ x = (16 + 3·y)/(-8) = -2 - 3·y/8
x = -2 - 3·y/8
Equating the two equations of 'x', gives;
5 - y/2 = -2 - 3·y/8
7 = y/2 - 3·y/8 = (4·y - 3·y)/8 = y/8
∴ 7 = y/8
y = 7 × 8 = 56
y = 56

In no less than one hundred fifty words, explain how microstructures reduce friction within fluid power systems. Mention some of the benefits of designing with microstructures.
Answer:
The functional surface on the microstructures reduces the friction. Below the functional surface, the layer surface will be there. It also reduces friction. The microstructures on the functional surface act as an oil reservoir and it produces the oil. It is well known that friction between lubricated surfaces is a chief source of energy Now, help is on the way due to research taking place within the Engineering Research Center for Compact and Efficient Fluid speed and lubricant type, and then choose the optimal microstructures.
