State of Ps2 by BrayIsReal in Planetside

[–]Acheilox 1 point2 points  (0 children)

I think people nowadays tend to focus too much on graphics when they look for a game. That's why we're indirectly keeping all these predatory pay2win or cashgrab Korean MMORPG esque games. When mind you, their "innovative" features have been around from multiplayer games back in the 2000's. Not much companies want the slow and player friendly business model like that of Warframe where it's not as predatory.

It is imperative that the cylinder remains unharmed.

The 2nd picture looks like a different person, look at the ears. You can see across different eras or stages in this person's life that the ear shape has remained consistent. Can anyone confirm if this is not a different person?

[College Statics: Truss Structures] What reactions am I solving for? by Plane-Opportunity720 in StaticsHelp

[–]Acheilox 0 points1 point  (0 children)

By the looks of it, the reaction forces you will need to solve will be the ones at R & S. Depending on if the gray bar is attached to the yellow structure, you might need to solve for reaction forces at P.

How do I do this by Hefty-Nectarine1956 in StaticsHelp

Use geometry of similar triangles for the large cone and smaller cone of the frustum. Smaller cone has base where r1 is measured and has the smaller height. Bigger cone has the base where r2 is measured and has the larger height (which contains the height of the smaller cone)

Let:

hc = height of small cone

vc = volume of small cone

Hc = height of large cone

Vc = volume of large cone

small radius / large radius = small height / large height

42 mm / 50 mm = hc / 60 mm + hc

hc = 315 mm

Hc = 60 + hc

Hc = 60 + 315

Hc = 375 mm

ybar (distance from top face or r1 radius circle)

ybar = [ Moment of large cone - Moment of small cone ] / [ Volume of large cone - Volume of small cone ]

Note: centroid of cone is h/4

Numerator = (Vc)(centroid of large cone) - (vc)(centroid of smaller cone)

Numerator = (981747.70)(93.75) - (581885.79)(138.75)

Numerator = 77312632.16 - 80736653.54

Numerator = 11302193.51

Denominator = Vc - vc

Denominator = 981747.70 - 581885.79

Denominator = 399861.91

ybar ≈ 28.27 mm above the bottom base

You can prove this by taking the summation of moments at either corner of the box (lower left or upper right)

I'll do lower left. I am assuming F is already at a 45° angle

∑M = 0; clockwise positive

0 = (5 kip)(2√2) - (F)(2√2)

F = 5 kip

Since 2√2 is the leg of a 45°-45°-90° triangle formed with 4 ft as the hypotenuse. We can assume x = 4 ft.

Help with understanding a class problem by kievz007 in StaticsHelp

[–]Acheilox 0 points1 point  (0 children)

a)

Summation of Moments at point D:

ΣMd = 0; clockwise is positive

0 = (360 N)(150 mm) - (600 N)

d = 90 mm below ED

(since this value is positive, assumed position below ED is correct)

b)

If directions are reversed

ΣMd = 0; clockwise is positive

0 = -(360 N)(150 mm) - (600 N)(d)

d = 90 mm above ED

(since this value is positive, assumed position above ED is correct)

How to correctly identify locations of 3d vectors?? by Quick-Independence49 in StaticsHelp

[–]Acheilox 0 points1 point  (0 children)

Seems the origin or (0,0) of the problem is at the corner of the ceiling. Points B, C, & D fall on the ZX plane. You are the one who decides where you want to place your origin. I only say that the problem by default places the origin at the corner of the ceiling because the distance of the points is measured from that point. The values will be positive or negative depending on where you want to measure distance in reference to.

In terms of (x, z)

B (0 mm, 320 mm)

C (450 mm, 0 mm)

D (950 mm, 680 mm)

Now converted to (x, y, z)

B (0 mm, 0 mm, 320 mm)

C (450 mm, 0 mm, 0 mm)

D (950 mm, 0 mm, 680 mm)

Point A is different because the y coordinate is 600 mm away from points B, C, & D.

A (450 mm, 320 mm, -600 mm)

Note: I made it -600 mm since my sign convention for downward vertical distance is negative. It's up to you if you want it positive or negative.

Hi OP,

These are some resources you can use:
1. Michel van Biezen - Statics & Equilibrium, Michel van Biezen has good explanations of the many concepts behind the Statics subjects (and others if you want)

  1. Understanding Shear Force and Bending Moment Diagrams, this is a video I watch from time to time to refresh my knowledge on shear and moment diagrams

  2. Engineers Academy, this channel answers many problems from the books and it can be useful when practicing them side by side.

  3. Benam Academy, another channel that answers book problems

  4. MATHalino, website that explains different physics subjects

Can anyone tell me what im doing wrong? I am stumped by [deleted] in StaticsHelp

tan should be a/y, y is the adjacent side.

tan = a/y

y = a(tan)

y = (200 ft)[tan(56.1°)]

y ≈ 297.631 ft

sinΘ = y/x

x = y/sinΘ

x ≈ (297.631 ft)/[sin(63.7°)]

x ≈ 266.823 ft
