Kinematics of particles problems and solutions pdf

SAT

iragen [17]2 years ago

The acceleration of the pendulum mass D is; r"_d =  [x''(t) + lθ'' cos θ - lθ'² sin θ]i - l[θ'' sin θ - θ'² cos θ]j

<h3>What is Kinematics of particles?</h3>

Kinematics is the study of the geometry of motion of particles, rigid bodies, etc., disregarding the forces associated with these motions. However, Kinematics of a particle is the motion of a point in space.

From the sample problem, we can solve it using the (x, y, z) coordinate system to get;

r_c = x(t) i

r_d = [x(t) + l sin θ]i + l cos θ j

Finding the first derivative of r_d gives velocity as;

r'_d =  [x'(t) + lθ' cos θ]i - lθ' sin θ j

Taking the second derivative of r_d gives the acceleration as;

r"_d =  [x''(t) + lθ'' cos θ - lθ'² sin θ]i - l[θ'' sin θ - θ'² cos θ]j

A sample problem of kinematics of particles is;

A block C slides along the horizontal rod, while a pendulum attached to the block can swing in the vertical plane. Find the acceleration of

the pendulum mass D.

In terms of communication, information is expressed either as the content of a message or through direct or indirect observation. That which is perceived can be construed as a message in its own right, and in that sense, information is always conveyed as the content of a message.

Information can be encoded into various forms for transmission and interpretation (for example, information may be encoded into a sequence of signs, or transmitted via a signal). It can also be encrypted for safe storage and communication.

I add 3 odd numbers together to make 50 why am i incorrect
aalyn [17]
Adding odd numbers will only give you an even sum if the amount of numbers you added is an even number.

For example,
25 is an odd number. If you add 25, 2 times (2 is an even number) you will get 50 (an even number). If you add 25, 4 times (4 is an even number) you will get 100 (still, an even number)
However, if you add 25, 3 times (an odd number) you will get 75 (an odd number). If you add 25, 5 times (an odd number) you will get 125 (still an odd number).


Hopefully, that helped (: Sorry if I confused you lol

+23PTS! PDF Volume question -_- find diameter from the cylinder. I got 9 answer is 6 how???
Serga [27]

Answer: See below

Explanation:

For this question, we are given the volume, and we want to find the diameter. We have to work backwards to get our radius, then to find the diameter.

V=\pi r^2h         (Volume of cylinder)

72\pi =\pi r^2h      (The π cancel out)

72 =r^2(8)        (Plug in h=8)

9=r^2              (Divide 8)

r=3               (Square root of 9 is 3)

Now that we have our radius, we can find our diameter.

d=2r             (Equation for diameter)

d=2(3)\\          (Plug in r=3)

d=6yards     (Multiply)
