How a single force is resolved along the perpendicular axis acting an angle theta with horizontal?​

Nataly [62]3 years ago

Answer:

A single force, which is acting at angle θ from a horizontal axis, can be resolved into components which act along the perpendicular axis.

Consider the perpendicular axis x and y, where x represents the horizontal axis and y represents vertical axis.

The Force is resolved into 2 parts, one acts along x-axis and is represent by X. The other acts along y-axis and is represented by Y.

From the diagram we can see that the Force and its components X and Y makes up a right angles triangle, where θ is the angle from the x-axis

<h3 /><h3>Find X:</h3>

We know that:

cosθ = Base/Hypotenuse

cosθ = X/F

X = Fcosθ

<h3>Find Y:</h3>

We know that:

sinθ = Perpendicular/Hypotenuse

sinθ = Y/F

Y = Fsinθ

<h3>Relation of Force and its Components:</h3>

Force F can be represent by:

F = Fcosθ (along x-axis) + Fsinθ (along y-axis)

As they form a right angled triangle, we can use Pythagoras Theorem to show the relation between Force and its components.

Hypotenuse² = Base² + Perpendicular²

F² = X² + Y²

F² = (Fcosθ)² + (Fsinθ)²

F = \sqrt{(F\cos\theta)^2+(Fsin\theta)^2}

Where θ can be found by using any of the trignometric functions.

What is the best countermeasure against social engineering?
Mkey [24]

Answer:

Hello Monk7294!

Answer:

Employee education

Explanation:

The most important countermeasure for social engineering is employee education. All the employees should be trained to keep confidential data safe. As a part of security education, organizations have to provide timely orientation about their security policy to new employees. The security policy should address the consequences of the breaches.

53. The plan of a building is in the form of a rectangle with
schepotkina [342]

Answer: 150m

Explanation:

The following can be depicted from the question:

Dimensions of outer walls = 9.7m × 14.7m.

Thickness of the wall = 0.30 m

Therefore, the plinth area of the building will be:

= (9.7 + 0.30/2 + 0.30/2) × (14.7 × 0.30/2 + 0.30/2)

= 10 × 15

= 150m

For the system form of the basic laws, the momentum of a system can change as a result of: a. pressure acting on the system. b.
Ymorist [56]

Answer: F. All the above.

Explanation:

Basically, if an object is moving, it moves with a certain velocity and mass. Momentum of a body is a product of mass and velocity. The sum of momentum of individual bodies is equal to the entire system momentum. For instance, a block v is moving due to an applied force F, with a velocity V and the gravity g. Due to gravity, the weight is mg. Due to gravity, the weight is acting downward. Applied force is acting on the block surface area A.

Pressure = Surface force/Surface area.

Surface force is acting on the surface applied. So, acting pressure = Force applied/area.

Pressure and surface force is acting on the body. Body forces also act on the system. Forces due to gravity is also referred to as body force. As a result of weight of the box, Normal force produced by the rough surface is equal to the Weight. As a result of rough surface, frictional forces are produced which opposes the block to move forward. All the external forces create a net total force due to which the block move with a velocity and acceleration.

In Newton's second law, Ftotal is equal to mass × acceleration.

Therefore, we can conclude that momentum can change as a result of all these forces because mass × acceleration is related to total force and momentum is equal to mass × velocity.

Vera_Pavlovna [14]

Answer:

The predetermined overhead rate is 42 $/h.

Explanation:

The predetermined overhead rate is calculated by the estimated manufacturing overhead divided by the estimated machine hours.

Predetermined overhead rate = $357000/8500h = 42 $/h
