What caused Raising the arm laterally at he shoulder?
Raising the arm laterally at the shoulder is primarily caused by the contraction of the deltoid muscle. This muscle is responsible for abduction of the arm at the shoulder joint, allowing you to lift your arm out to the side. The action is coordinated by signals from the brain through the nervous system to the muscle fibers.
In motor unit summation how many motor units are required to lift weight of 160 and 80?
The amount of motor units that is needed to lift 160 pounds will be greater that the number required when lifting 80 pounds. This is due to the nervous system reading the situation and determining the number of units required. The smaller the muscle, the more delicate the control can be.
Which type of neurone transmits a signal from a sense organ to the central nervous system?
like say this if you put your hand on top of a burning candle the heat will burn your hand and your nerve system will feel it and then it will send a signal up from your hand to your spinal cord and then the massage from your spinal cord will get sent up to your brain telling it what has happened and then the brain will send another massage down our spinal cord into your hand which will tell your muscle to lift up your arm away from the burning candle
How do you use skidding tongs?
Skidding tongs are used to grip and lift logs for skidding or dragging purposes. To use them, attach the tongs securely to the log using a chain or cable. Make sure the tongs are firmly clamped onto the log before attempting to lift or move it using a skidder or winch.
How does movement happen in your body?
Your brain (you) sends electrical messages to muscles through the nervous system, which makes certain muscles contract and make you move. Like when you lift your finger your brain sends a signal to a muscle in your arm which pulls the tenant that lifts it up. Also, sperm whale.
How does your brain help you lift a chair?
Your nervous system contacts your brain to tell your hands to lift the chair.
Is alcohol a general stimulation of the brain and body?
Alcohol is a central nervous system depressant. It stimulates nothing. The temporary "lift" is psychological.
When you lift very heavy weights what pulley system are you using?
Single Moveable
What pulley system will lift the weight using the least amount of effort force?
A compound pulley system using multiple pulleys will require the least amount of effort force to lift a weight. The mechanical advantage of a compound pulley system increases with the number of pulleys, reducing the amount of force needed to lift the weight.
A load can be lifted easily by?
A load can be lifted easily by using a pulley system.
How much force to lift 100 lbs using 2 pulleys?
Using 2 pulleys in a block and tackle system reduces the amount of force needed to lift the weight by half, so it would require 50 lbs of force to lift a 100 lb weight. The mechanical advantage of the system allows the load to be distributed among multiple lines, making it easier to lift heavy objects.
What is one advantage of using a pulley system?
One advantage of using a pulley system is that it can help to reduce the amount of force needed to lift a heavy object. By distributing the load across multiple ropes and pulleys, the effort required to lift the object is decreased.
Why is it easier to lift heavy objects using a pulley system?
A pulley system allows for the weight of the object to be distributed across multiple ropes and pulleys, reducing the amount of force needed to lift the object. This makes it easier to lift heavy objects as the force required is decreased due to the mechanical advantage provided by the pulley system.
How can a kayak pulley system be used to efficiently lift and store a kayak?
A kayak pulley system can be used to efficiently lift and store a kayak by attaching the pulleys to a ceiling or overhead beam, then using ropes and hooks to lift the kayak off the ground. This system allows for easy storage and saves space in a garage or storage area.
How do you you lift a heavy object without a forklift?
To lift a heavy object without a forklift, you can use techniques like using a lever and fulcrum, using a hoist or pulley system, or using a dolly or hand truck to help with moving the object. Make sure to use proper lifting techniques and get assistance if needed to prevent injuries.
Why it is easier to lift the same load by using three -pulley system than two-pulley system?
A three-pulley system allows the load to be distributed among three supporting strands, making it easier to lift the load as each strand bears less weight compared to a two-pulley system where the load is evenly distributed between only two strands. The mechanical advantage of the three-pulley system reduces the amount of force required to lift the load, making it easier to lift.
What is making it easier to lift the load?
Using a pulley system or mechanical advantage devices like levers or ramps can make it easier to lift a load by spreading the force over a larger distance or reducing the amount of force needed. Additionally, utilizing tools like forklifts or cranes can also help to lift heavy loads with less effort.
