Calculate the moment if you were to hold a 15lb bowling ball with your arm straight out and your forearm perpendicular to your body. What is the pinnned connection

Would that make the shoulder the pinned connection?

The moment (about the shoulder) is the weight times the arm length from the ball to your shoulder

The hinge is at the shoulder all right.

Thank you (:

Well, if you hold a 15lb bowling ball with your arm straight out, you'll definitely feel the "moment" of regret in your muscles! As for the technical moment you're referring to, it's called the "moment of force" or "torque."

To calculate it, we need the distance from the pivot point (your shoulder joint) to the center of the bowling ball. Let's assume for simplicity's sake that it's 2 feet (24 inches).

Now, we need to convert that pesky 15lb weight into a more practical unit: laughter. According to the International Bureau of Silly Conversions, 15lb is equivalent to approximately 4 giggles per ounce. So, our 15lb bowling ball can produce a whopping 960 giggles!

Multiplying that by the distance (24 inches) in our formula, we get:

Moment = 960 giggles × 24 inches

But wait, there's more! In order to account for the perpendicular forearm angle to your body, we need to introduce a "Humor Coefficient" of 0.75 (because the funniest moments are rarely perfect).

Final Moment = 960 giggles × 24 inches × 0.75

Voila! You now have the moment of holding that bowling ball. Remember, the beauty of humor is that it lightens up any moment, even if it's a physics calculation!

To calculate the moment when holding a bowling ball with your arm straight out and your forearm perpendicular to your body, we need to understand the concept of the moment of force.

The moment of force, also known as torque, is a measure of the turning effect produced by a force applied at a certain distance from a pivot point. In this case, the pivot point is the joint connecting your forearm to your upper arm.

To calculate the moment, we need two factors: the force applied and the distance from the pivot point.

1. Force: The weight of the bowling ball is given as 15lbs. Since we're assuming you're holding it straight out, the force applied is equal to the weight, which is 15lbs.

2. Distance: The distance from the pivot point (the joint connecting your forearm to your upper arm) to the center of the bowling ball will determine the moment.

Now, let's assume that the distance from the pivot point to the center of the bowling ball is d. To measure this distance, you can use a measuring tape or ruler.

Once you have the distance (d), the moment can be calculated using the following formula:

Moment = Force × Distance

Substituting the given values:

Moment = 15 lbs × d

Therefore, the pinned connection in this scenario is the joint connecting your forearm to your upper arm.
