Force Required To Cut Through Plastic: Understanding The Science

Cutting plastic requires a lot of force. It takes more force than you can deliver with a pair of scissors, for example. The amount of force required depends on the type of plastic and the tool used to cut it. The force can be calculated using the equation F = A x Ss, where F is the cutting force, A is the shear area, and Ss is the shear strength.

The force required to cut plastic can be calculated using the equation F = A x Ss, where F is the cutting force, A is the shear area, and Ss is the shear strength

It's important to note that cutting hard plastic requires more force than can be delivered with a pair of scissors. Scissors may slip against the smooth surface of the plastic rather than cutting through it. To cut thick plastic, a string can be used by jerking your hands outward with medium force while holding the string. The durability of the string can be tested by seeing if it flexes slightly and doesn't snap when subjected to this force.

Shearing force is a type of force that occurs when two objects move or slide against each other in opposite directions

To calculate the shearing force required to cut plastic, you can use the equation F = A x Ss, where F is the cutting force, A is the shear area, and Ss is the shear strength. The shear area is the product of the thickness of the plastic and the length of the blades used for cutting. For example, if the thickness of the plastic slab is 0.01m and the length of the blades is 0.6m, then the shear area would be 0.01 x 0.6 = 0.006 square meters.

The shear strength of the plastic is a measure of its resistance to shearing forces. It can be determined by testing the plastic's ultimate tensile strength, which is the maximum stress it can withstand without breaking. For example, if the ultimate tensile strength of the plastic is 70 MPa, then the shear strength is assumed to be equal to the tensile strength, which is 70 MPa.

By substituting the values of A and Ss into the equation F = A x Ss, you can calculate the cutting force required to cut the plastic. In this case, the cutting force would be 0.006 square meters x 70 MPa = 0.42 N/m^2. This means that a force of 0.42 Newtons per square meter is required to cut through the plastic slab with a thickness of 0.01 meters using blades with a length of 0.6 meters.

It's important to note that the force required to cut plastic can also depend on other factors such as the temperature and the sharpness of the cutting tool. Additionally, there are alternative methods to cut plastic, such as using a string. By clamping the plastic firmly and jerking your hands outward with medium force while holding the string, you can slice through the plastic without the need for scissors or blades.

Cutting hard plastic takes more force than can be delivered using a pair of scissors

The amount of force required to cut plastic depends on the type of plastic and its thickness. The force required to cut plastic can be calculated using the equation F = A x Ss, where F is the cutting force, A is the shear area, and Ss is the shear strength.

One way to cut through plastic is to use a string. You'll need a section of string about 2 feet (61 cm) long. Hold the plastic tightly between your knees or use a C-clamp to hold it to a worktable. Jerk your hands outward with medium force while holding the string. If it flexes slightly and doesn't snap, it will cut through the plastic.

The amount of force needed to cut plastic depends on the type of plastic and the tool used. For example, cutting hard plastic takes more force than can be delivered using a pair of scissors. Scissors will slip against the smooth plastic rather than cutting it.

The force required to cut plastic can be determined using a force gauge or load cell

The amount of force needed to cut plastic depends on the type of plastic and the tool used to cut it. For example, scissors are not strong enough to cut through hard plastic, and the plastic will likely slip against the blades. However, a string can be used to cut through plastic with a medium amount of force.

The equation for calculating the force required to cut plastic is F = A x Ss, where F is the cutting force, A is the shear area, and Ss is the shear strength. This equation assumes that the plastic is spread all over the blades, maximising the cutting action.

The Merchant's circle model can also be used to calculate the theoretical cutting forces without performing an experiment.
