A gear train has a ratio of 40/24 and the driving gear is turning 100 RPM.
What is the speed of the driven gear in RPM?
Answer:
S2 = 60 RPM.
Explanation:
Given the following data;
Gear ratio = 40/24 (T2 = 40 and T1 = 24).
Speed of driving gear = 100 RPM
To find the speed of the driven gear;
Mathematically, gear ratio in terms of speed (RPM) is given by this formula;
[tex] S_{1} * T_{1} = S_{2} * T_{2} [/tex]
Where;
S1 represents the speed of the driver gear.S2 represents the speed of the driven gear.T1 represents the number of teeth of the driver gear.T2 represents the number of teeth of the driven gear.Substituting into the equation, we have;
[tex] 100 * 24 = S_{2} * 40[/tex]
[tex] 2400 = 40S_{2} [/tex]
[tex] S2 = \frac {2400}{40} [/tex]
S2 = 60 RPM.
Therefore, the speed of the driven gear is 60 revolutions per minute.

a torque of 24 ft pounds is the result when a force of ______ pounds is applied to a wrench that is 18 inches long.
Answer:
16
Explanation:
The product of feet and pounds is the torque. 18 inches is 1.5 feet.
(1.5 ft)(x lbs) = 24 ft·lbs
x lbs = (24 ft·lbs)/(1.5 ft) = 16 lbs
The force will be 16 pounds applied to an 18-inch wrench to obtain 24 ft·lbs.
Answer:
16

2. It is a measuring instrument used to record the amount of
electrical consumption.
A. clamp meter B. micrometer
B.micrometer
C. steel rule
D. electric meter
Answer:
The correct option is;
D. Electric meter
Explanation:
An electric meter is a metering device that is used for the measurement of the electric power consumption of an electrical powered tools, a living space or a building
Electric meter readings are used by electric utility company to sell electric power to consumers at a given rate such that it allows the electric utility company to receive payment for the total power supplied, and for the consumer to regulate the amount of power consumed
The electric meters are usually calibrated in kilowatt hour (kWh) and prepaid meter displays the amount of units of power bought, while post paid meters are usually read once each billing period which is usually one month.

Can someone teach me how to find all valid minterms of any given truth table?
Explanation:
A minterm is a product of variables, in which each variable appears exactly once, either complemented or not. When a truth table is represented in a sum of products form, there is one minterm for each line in the table for which the output is True (1).
Suppose I have a truth table as follows, with inputs A, B and output Z.
AB Z
00 1
01 0
10 1
11 0
When I write the minterms, I use a complemented variable where the input is 0, and an uncomplemented variable where the input is 1. The minterm is expressed as a product of those variables.
Here, there are 2 lines in the table with outputs Z=1. The input conditions AB for those outputs are 00 and 10, so the corresponding minterms are A'B' and AB', where the apostrophe indicates the variable is complemented.
This table is then represented by the sum of products ...
Z = A'B' + AB'
You have all of the valid minterms when you have one for each line of the table where the output is 1.
__
Comment on truth table representation
Truth tables can be represented a number of ways. A nice representation for the purpose of identifying minterms is a list of the output for every possible combination of inputs. We have used that form above.
Sometimes, you may see minterms listed as decimal numbers in the range of 0 to 2^n -1 when there are n input variables. Then, the minterms are developed from the binary equivalents of those decimal numbers.
Example:
Logic with 4 input variables has minterms 7, 8, and 15. The binary equivalents of these numbers are 0111, 1000, 1111. The corresponding minterms (for inputs a, b, c, d) are a'bcd + ab'c'd' + abcd = z. Three numbers are listed, so we know we have all of the valid minterms when we have three corresponding minterms.

Additional comment
In some cases, outputs will be listed as "don't care." Another set of minterms can be generated for the don't cares. These can be used in the logic minimization process.

which of the following best describes the mechanical energy of an object?
In other words, an object possesses mechanical energy when it has the ability to do work due to its position or motion. Mechanical energy can take the form of either kinetic energy, which is energy due to an object's motion, or potential energy, which is stored energy due to an object's position.
Some examples of mechanical energy are:
Hydro power plantCyclingWrecking balls, etcWhat is Mechanical Energy?This refers to the type of energy that an object or mass possesses based on its motion and can either be potential or kinetic energy.
Therefore, mechanical energy can be represented mathematically as: [tex]E_{mechanical}[/tex] = U + K
Where U= potential energy
K= kinetic energy
