Answer:

The mechanical advantage = 4/75

Explanation:

A wheel barrel is a second class as the effort is placed further from the point of fulcrum than the point of action of the load

The parameters given are;

Length of wheel barrel = 4 cm

Distance between wheel and center of load = 0.75 m

Therefore, we have the mechanical advantage, MA given as follows;

[tex]MA = \dfrac{F_{o}}{F_{i}} = \dfrac{L_{i}}{L_{o}}[/tex]

[tex]{F_{o}}[/tex] = Output force

[tex]{F_{i}}[/tex] = Input force

[tex]{L_{o}}[/tex] = Distance from output force =  0.75 m

[tex]{L_{i}}[/tex] = Distance from input force = 4 cm = 0.04 m

Therefore;

[tex]MA = \dfrac{0.04}{0.75} = \dfrac{4}{75}[/tex]

The mechanical advantage MA = 4/75 = 0.0533

Therefore, more force (75/4 × the load) will be required to lift a given load.

An electric car. Probably, I don't know, am I correct? please give me brainliest if I am.

Technician A is correct as the four strokes make up the complete combustion cycle in internal combustion engines.

Technician A is correct in stating that the four strokes of the four-stroke cycle are intake, compression, power, and exhaust. These four strokes make up the complete combustion cycle in internal combustion engines.

Technician B's statement about most engines rotating clockwise as viewed from the rear flywheel end of the engine is not relevant to the question about the four-stroke cycle.

The rotation direction of the engine does not affect the order or definition of the four strokes.

Therefore, Technician A is correct.

Answer:

"D

Explanation:

The process that does a professional use to find an object’s position with respect to the camera is tracking. The correct option is D.

Any shot where the camera moves beside the subject being filmed while moving forward, backward, or side to side is a tracking shot.

The word refers to a scene in cinematography when the camera is mounted on a dolly and then moved along rails to resemble a train track.

A "tracking shot" is a recording in which the camera moves in sync with the action being captured.

Dolly shots and tracking shots can sometimes be confused, but you can tell them apart by the path they follow. Tracking pictures typically move with the subject along the horizontal axis.

Tracking is the technique used by experts to determine an object's location in relation to the camera.

Thus, the correct option is D.

Answer:

The amount of rains that can be stored in the two silos combined is 5242.53 ft³

Explanation:

The parameters given are;

Diameter, D, of the silos = 15 feet

Height, h₁, of the larger silo = 18 feet 10 inches = 18.83 feet

Height, h₂, of the shorter silo = 10 feet 10 inches = 10.83 feet

The volume, V, of the cylindrical shape is given by the formula;

Volume = Area of base × Height

[tex]Area \, of \, the \, base = \pi \times \dfrac{D^{2}}{4}[/tex]

[tex]\therefore Volume = \pi \times \dfrac{D^{2}}{4}\times h[/tex]

Therefore, for the larger silo, we have;

[tex]Volume, V_1 = \pi \times \dfrac{D^{2}}{4}\times h_1[/tex]

[tex]V_1 = \pi \times \dfrac{15^{2}}{4}\times 18.83 = 3328.12 \ ft^3[/tex]

for the shorter silo, we have;

[tex]Volume, V_2 = \pi \times \dfrac{D^{2}}{4}\times h_2[/tex]

[tex]V_2 = \pi \times \dfrac{15^{2}}{4}\times 10.83 = 1914.41\ ft^3[/tex]

The amount of rains that can be stored in the two silos combined = 3328.12 ft² + 1914.41 ft² = 5242.53 ft².

Explanation:

The National Highway Safety Act establishes general guidelines concerning licensing, vehicle registration and inspection, and traffic laws for state regulations. The act was made in 1966 to reduce the amount of death on the highway as a result of increase in deaths by 30% between 1960 and 1965

National Traffic and Motor Vehicle Safety Act regulates vehicle manufacturers  by ensuring national safety standards and issuance recalls for defective vehicles

Uniform Traffic Control Devices Act  defines shapes, colors and locations for road signs, traffic signals, and road markings

Tech B says that the long-term trim values can be positive or negative is correct while tech A is wrong.

When the displayed fuel trim value is said to be negative number, it implies that the ECU is reducing the injector pulse scope to remove fuel from the air or fuel mixture.

Therefore, Tech B says that the long-term trim values can be positive or negative is correct while tech A is wrong.

So, option B is correct.

Answer:mechanical advantage is the ratio produced by a machine to the force applaide to it.

Explanation:

Answer:

Explanation:

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever.
