Shock cord has a 100% elongation or can stretch to double its original length, while elastic cord has a 50% elongation or can stretch to one and a half times its original length.

How do you calculate the extension of a bungee cord?
Equating these expressions gives mgh = 0.5kx^2. This assumes that all of the gravitational potential energy of the bungee jumper will be converted to elastic potential energy. To find the maximum extension of the rope, rearrange this expression to find x, giving x = (2mgh/k)^0.5.
How do you calculate bungee jump?
How does bungee jumping work physics?
The bungee jump can then be divided into three phases: (i) a free-fall (with acceleration of gravity g) of the jumper, when the rope is still slack; (ii) the stretch phase until the rope reaches its maximum length; and (iii) the rebound phase consisting of a damped oscillatory motion.
How far will a 40 bungee cord stretch?
2. A: Maximum safe stretch length is 50% longer than relaxed length. Example: 40″ strap has a maximum safe stretch to 60″.
How much does 24 bungee cord stretch?
Product Details The 24″ Easy Stretch Bungee Cord can stretch to 48″.
How does Hooke’s law relate to bungee jumping?
Hooke’s Law tells us that the elastic bungee cord will stretch by a known amount for each person depending on their weight. Elastic objects stretch by the same amount each time we add the same amount of weight or force until it reaches its elastic limit.
Why does a bungee cord stretch as well as it does 1 point?
As you stretch or compress an elastic material like a bungee cord, it resists the change in shape. It exerts a counter force in the opposite direction. This force is called elastic force. The farther the material is stretched or compressed, the greater the elastic force becomes.
Will a bungee cord forever hold its shape?
After the elastic limit is an area called the plastic region. The object may be stretched further in this area, however it will not returned to its original shape and will be permanently distorted. Eventually, the object will reach its breaking point.
How much G force is bungee jumping?
The position y = -L is the point where acceleration a is maximum. For example, if the bungee cord weighs the same as the bungee jumper the maximum acceleration is approximately 1.6g.
What is bungee jumping answer?
Bungee jumping (/หbสndสi/), also spelled bungy jumping, is an activity that involves a person jumping from a great height while connected to a large elastic cord.
Is bungee jumping simple harmonic motion?
Bungee jumping is a good example of simple harmonic motion. Bungee jumping companies have a variety of cords so that people of different weights can take the jump without hitting the bottom. It’s similar to the egg drop lab that we did, but with different variables, and the height of the drop being the constant.
Which force helps in bungee jumping?
The gravitational force is almost exactly constant throughout the jump. During the bungee jumper’s fall, he or she also experiences a force due to air resistance. The faster the jumper is falling, the more the air resistance pushes back opposite to the direction of motion through the air.
What energy is involved in bungee jumping?
There are 3 forms of energy during a bungee jump, kinetic (KE = 0.5mv^2), gravitational potential (GPE = mgh) and elastic potential (EPE = 0.5kx^2). Energy is conserved throughout, and it’s assumed none is lost as heat due to air resistance.
What energy transfers happen in a bungee jump?
As the jumper rises, the energy in the elastic potential energy store of the rope decreases and the bungee jumper’s kinetic energy store increases until the rope becomes slack. After the rope becomes slack, and at the top of the ascent, the bungee jumper’s kinetic energy store decreases to zero.
How far does a 30 in bungee cord stretch?
Product Description 24″ (30″ incl hooks) – up to 138″ (11.5 ft.) SuperBungee Cords stretch 6 to 10X further and are much stronger than typical bungee cords! You no longer need to buy multiple sizes of cheap, flimsy bungee cords that don’t last! Great unique gift!
How far will a 32 inch bungee cord stretch?
Super Bungee – 32″ Long Bungee Cord (38″ with hooks) | Stretches To 15 Feet.
How far will a 48 bungee cord stretch?
A: Allie- The limit of bungee cords is 50 % stretch on the original length. So this bungee cord that is 48″ will stretch an additional 24″ for a total stretched length of 72″. For safety the cord should not be stretched beyond this.
How long does shock cord last?
Stored right the shock cord should last at least a few years. One caution to share from a friend’s experience โ he stored his tent and other gear in an attic that would heat up more than the rest of the house โ definitely reduced the life of elastic cord, PU materials and glues in footwear.
Can a bungee cord break?
A bungee cord should never be stretched more than twice its resting length. Even with normal use, bungee cords will eventually stretch permanently, fray, or break as exposure to sun, rain, wind, and extreme temperatures can accelerate a cord’s deterioration.
How strong is bungee cord?
Shock cord, commonly known as bungee cord, is available in a variety of diameters ranging from 1/8 inch with a tensile strength of 100 pounds to 1/2 inch with a tensile strength 450 pounds.
Does a bungee cord follow Hooke’s Law?
In conclusion, while the cord does exhibit some spring-โlike behaviors, it does not exactly follow Hooke’s law and should not be treated as a spring.
Is bungee jumping an oscillation?
The above described phenomenon is known as a damped oscillation and in the case of bungee jumping, a lightly damped oscillation will occur, whereby the displacement against time graph of the system will show a exponentially decaying envelope.
What happens to a material when it is stretched or compressed beyond its limit?
The farther the material is stretched or compressed, the greater the elastic force becomes. As soon as the stretching or compressing force is released, elastic force causes the material to spring back to its original shape.
Is shock cord the same as bungee cord?
Bungee cord, shock cord, and elasticated cord are three names that are used interchangeably, to describe a cord with a stretchy rubber core and a braided outer sheath. In fact, all of the bungee cords available on our site are actually listed as shock cords, because they’re exactly the same thing!
