The spine of an arrow is not expressed in "weight" - it is the bow's pulling power that is expressed as a weight figure. The arrows must suit this weight.
Any bow takes a certain amount of force to draw back to the normal shooting position (usually with the string touching the chin and nose); this force is measured in x number of pounds - my own ash longbow is lighteweight at just 45 pounds draw weight.
In order for the arrows to fly true, they must have a certain amount of flexibility ("spine") to match the draw weight of the bow - if they are too flexible they will shoot off to the right, if too stiff they will go left of the target. This is due to the so-called "archer's paradox" where the arrow first bends itself around the bow handle and then continues to fly straight.

Can you use a 65-75 arrow with a 50 lb draw weight?
Your arrow should match the draw weight. In your case the "spine" or stiffness will be too much. Assuming the arrow was matched to begin with.

How much weight can a spine support before it will break?
Depends on the devellopment of the spine, the length of the spine, the strength of the muscles involved at the point where the weight is on the spine. Depends on the shape and the material of the weight. Cant be answered like this. Go look at weightlifting contests by supermans on eurosport.
What is the diet modification of a patient with herniated nucleus pulposus?
Diet modification would be essentially losing weight to take any undue stress off your lower spine. The excess weight, particularly around the midsection or abdomen places more stress on your lower spine. Especially around the L4/L5 area of the lumbar spine. If you were to lose this weight, it is thought that by reducing this load, there will be less weight bearing stress on this part of the spine.
What are the advantages of the spine being curved?
It is stronger than it would be if the spine/vertebral column were straight.Allows for distribution of weight and flexibility of movement.
When a person sits What is supporting the weight?
When sitting, the weight of a person is supported by the lower spine, the hips and the buttocks.
What is lordotic?
Lordotic refers to the "lordotic curvature" of the spine. Lordotic curvature of the spine is the natural curves of the spine (when viewed from the side) that allow for even weight distribution and optimal shock absorbing properties.

What is the medical term for anterior curvature of the spine?
The medical term for anterior curvature of the spine is lordosis. It is a normal curve in the cervical and lumbar regions of the spine that helps distribute weight and maintain balance.
What joint bares the most weight in the body?
knees hips spine hands
Why does the spine curve during pregnancy?
Your spine naturally has curves even before pregnancy. The spine consist of 4 specific curves: Cervical curve, Thoracic curve, Lumbar curve, and Pelvic Curve Curves in the spine provide support for the weight in the human body, and also make it easy to balance this weight. The spine also help balance your head and give structure support to your ribs. It may seem like you notice the curves more since you have "extra baggage" that may put pressure on spine.
How do you draw an elevator free body diagram?
Draw an arrow pointing upwards for the tension force and an arrow pointing downwards for the weight of the elevator which will be its mass times gravity (mg). Also, draw another arrow pointing downwards for any mass that may be inside the elevator (another mass times gravity arrow but for a separate weight) and add that value to that of the weight of the elevator. Depending on the direction that the elevator is moving (up or down) draw another arrow respectively and label it "a" for acceleration.
