CATENARY Calculator - Chain curve

With the CATENARY Trigonometric Function Calculator, you can calculate catenary chain curve values. In addition to the response results, the calculator will also plot the selected function. You can choose a ready-made function, e.g. cat(?#X) where for ? you will substitute e.g. 2 for catenary two which will be equal to 2*cosh(x/2) or enter your own function e.g. cat(2#x^2) for 2*cosh((x^2)/2), cat(2#x+3) for 2*cosh((x+3)/2) etc.

Playing with the recognition of color shades - an eye test.

The calculator is used to test your eyesight and recognize the difference in color shades. After clicking on the first lighter field, the calculator will change colors and the countdown will begin. Each test takes 15 seconds. Search for a lighter field and click on it. Each subsequent test is more difficult. The test will be aborted if you do not give the correct answer within 15 seconds or if you make a wrong choice three times.

Brinell hardness scale

With this calculator you can calculate the HB hardness or the hardness of metals based on the Brinell hardness test.

Vertical projectile motion - speed, time, height

With this calculator, you can calculate the velocity of a body thrown vertically after a specified time and the initial velocity given to the body. You will also calculate the time elapsed from the moment of the throw to reach a certain speed, the time the body flies to the return to the place of the throw and the time after which the body reaches its maximum height. The calculator will also help you calculate the height at which the body is located after a certain time and will calculate the maximum height that the body will reach. The calculator also allows you to estimate the gravitational acceleration which can be useful in determining where the body was thrown.
