Calculating G-Force at A and B in 8'X4'X4' Box with 300Kg Weight

The formula for calculating G-force is force/mass, but without knowing the specific forces involved, the exact formula cannot be determined. In summary, it is not possible to calculate the G-force without more information.

According to the attached picture, is it theoretically possible to measure the G-Force pulled in A and B (taking that A and B are at respectively the very top and the very bottom of the box)? If it is possible, what would be the formula ( I don't want the answer, because it is all hypothetical, i just want the formula)?
Caracteristics:
- the head of the device spins at 20 RPM
- the size of the box is 8'X4'X4'
- the diameter of the head of the device is 2'
- The diameter of the outer ring of the device is 10'
- the pipes holding the boxe are 15'
- the device is 15' high from base to top
- the box weighs 300Kg

Outside Factors:
- there is no wind

Thanks for your help

Based on the given information, it is theoretically possible to calculate the G-force at points A and B in the 8'X4'X4' box with a 300kg weight. The formula for calculating G-force is:

G = (ω^2 * r) / g

Where:
G = G-force
ω = angular velocity (in radians per second)
r = radius from the center of rotation to the point of interest
g = acceleration due to gravity (9.8 m/s^2)

In this case, the angular velocity (ω) can be calculated by converting the 20 RPM to radians per second using the formula:

ω = (2π * RPM) / 60

The radius (r) can be determined by subtracting the radius of the head of the device (1') from the radius of the outer ring (5').

Assuming point A is at the very top of the box and point B is at the very bottom, the radius for point A would be 4' (15' - 11') and the radius for point B would be 1' (15' - 14').

Plugging in the values, the formula for calculating G-force at point A would be:

G at A = [(2π * 20/60)^2 * 4'] / 9.8 m/s^2

And the formula for calculating G-force at point B would be:

G at B = [(2π * 20/60)^2 * 1'] / 9.8 m/s^2

Please note that the units for angular velocity and radius should be consistent (either in radians or meters) in order to get the correct result.

It is important to keep in mind that this is a theoretical calculation and may not accurately reflect the actual G-force experienced in this scenario. Other factors such as friction and air resistance may also affect the G-force measurement.
 

1. How is G-Force calculated in a specific box with a known weight?

G-Force is calculated by dividing the weight of the object (in kilograms) by the force of gravity (9.8 m/s²). In this case, the weight is 300 kilograms, so the G-Force would be 300 kg / 9.8 m/s² = 30.6 G.

2. Does the size of the box affect the G-Force calculation?

Yes, the size of the box does affect the G-Force calculation. The G-Force is calculated based on the weight and the force of gravity, but the size of the box can also impact the distribution of the weight and the overall acceleration experienced by the object.

3. How does the weight of the object impact the G-Force calculation?

The weight of the object is a crucial factor in calculating G-Force. The greater the weight of the object, the greater the force of gravity acting on it, resulting in a higher G-Force calculation.

4. Is it possible to calculate G-Force without knowing the weight of the object?

No, the weight of the object is necessary to accurately calculate G-Force. Without knowing the weight, it is not possible to determine the force of gravity acting on the object, which is a key component in the G-Force calculation.

5. Can G-Force be negative?

Yes, G-Force can be negative. This occurs when the acceleration of the object is in the opposite direction of the force of gravity. In the given scenario, the G-Force would be negative if the object was accelerating upwards with a force greater than the force of gravity pulling it downwards.
