it would be messed up if they gave you a ticket
no
an arm is for grabbing stuff. it is only useful if you have a hand though.
So long as you can control the car safely, yes. Some drivers have only 1 arm.
Yes, it depends on what part of your body is restricted and also if it affects your feet. But if it is just a arm cast, learn to drive with your other hand.
Only a very small force if the arm only has to be supported. What other weights do the arm carry and at what angle does the biceps attach to the fore-arm? What is the distance to the hand from the fulcrum and what is the arm weight (assuming a weight is in the hand and arm weight has to be added to the weight-in-hand)? The length of the hand to fulcrum is also required. There is no such thing as 90% angle: 90 degrees perhaps?
Your thumb is connected to your hand and your hand is connected to your arm.
Is it legal to drive with a cast on your arm
I assume it would be the hand because the arm is less used and the hand has at least 50,000 senses and is a main sense it would be handin conclusion, the hand would be the main and best answers for this particular question concluding that the arm is from bottom hand to arm socket

An arm is what you used to type the question. The hand is what I used to type this answer.
