Answer:

The component of F along AB is equal to Fcos45

F = 520N

Component along AB = 520cos45

= 367.7N

This is done by rotating the diamonds such that AB is now taken as the x-axis. Then the force F is resolved along AB.

Answer:

Force AB = 466.2N

Force AC = 380.7N

Complete Question:

The vertical force F acts downward at A on the two membered frame. Determine the magnitude of the component of F directed along the axis of AB . Set F=520 N

Determine the magnitude of the component of F directed along the axis of AC.

Attached is the image of the question.

Explanation:

Given the force distribution in the image attached:

Let X represent force AB and Y represent force AC

F = 520N

Resolving the force distribution to the vertical and horizontal components.

For vertical component (x axis)

F = Xcos45 + Ycos60 .....1

For horizontal component ( y axis)

Xsin45 = Ysin60 .....2

From equation 2

Y = Xsin45/sin60 ....3

Substituting equation 3 into equation 1

F = Xcos45 + (Xsin45/sin60)cos60

F = X ( cos45 + (sin45/sin60)cos60)

X = F/ ( cos45 + (sin45/sin60)cos60)

Substituting F = 520N and solving for X

X = 520/ ( cos45 + (sin45/sin60)cos60)

X = 466.2N

From equation 3.

Y = Xsin45/sin60

Y = 466.2sin45/sin60

Y = 380.7N

Therefore,

Force AB = 466.2N

Force AC = 380.7N

A busy chipmunk runs back and forth along a straight line of acorns that has been set out between his burrow and a nearby tree.
saveliy_v [14]

Answer: a = 1.32m/s2

Therefore, the average acceleration is 1.32m/s2

Explanation:

Acceleration is the rate of change in the velocity per time

a = change in velocity/time

a = ∆v/t

average acceleration a = (v2 -v1)/t. ....1

Given;

Final velocity v2 = 1.63m/s

Initial velocity v1 = -1.15ms

time taken t = 2.11s

Substituting into eqn 1

a = [1.63 - (-1.15)]/2.11

a = (1.63+1.15)/2.11

a = 2.78/2.11

a = 1.32m/s2

Therefore, the average acceleration is 1.32m/s2

The loaded cab of an elevator has a mass of 3.0 x 10 3 kg and moves 200 m up the shaft in 20 s at constant speed. At what averag
Alexeev081 [22]

The average rate at which the cable does work is 294,000 J/s.

The given parameters:

  • <em>mass, m = 3000 kg</em>
  • <em>height, h = 200 m</em>
  • <em>time of motion, t = 20 s</em>

The average rate at which the cable does work is calculated as follows;

P = \frac{E}{t} \\\\P = \frac{mgh}{t} \\\\P = \frac{3000 \times 9.8 \times 200}{20} \\\\P = 294,000 \ J/s

Thus, the average rate at which the cable does work is 294,000 J/s.

The United States spends over $20 billion a year on space exploration through NASA. Do you think that this has been worth the co
-BARSIC- [3]

Sunday, July 20, marked 45 years since the United States put the first two astronauts safely on the moon. The cost for the Mercury, Gemini and Apollo programs was more than $25 billion at the time more like $110 billion in today’s world. The ensuing U.S. space efforts have cost an additional $196 billion for the shuttle and $50 billion for the space station. NASA’s total inflation-adjusted costs have been more than $900 billion since its creation in 1958 through 2014 (more than $16 billion per year). Looking back, have we gotten our money’s worth from the investment?

According to ____, the ability to detect a stimulus depends not only on the intensity of the stimulus but also on other variable
irakobra [83]

Answer:

Signal detection theory

Explanation:

Signal detection theory states that stimulus ca be detected according to its intensity and a person's psychological and/or physical state. This means that we can notice things according to how strong they are but also, a person's characteristics like experience and physiological state like fatigue can affect the ability to detect them.

Because of this, the answer is that according to signal detection theory, the ability to detect a stimulus depends not only on the intensity of the stimulus but also on other variables such as the level of noise in the system and your expectations.
