THREAD CUTTING - Practice Mode
1) What is the minor diameter of Trapezoidal square thread Tr 40 x 7 depth clearance of 0.01 mm?
Explanation:
The area of a sector of a circle can be calculated using the following formula:
Area of sector = (Angle of sector / 360) x (pi x (radius)^2)
where the angle of the sector is measured in degrees and the radius is measured in the same units (e.g. cm).
Given the radius of 5 cm and an angle of 96 degrees, we can substitute the values into the formula and calculate the area:
Area of sector = (96 / 360) x (pi x (5)^2) Area of sector = (0.2667) x (pi x 25) Area of sector = (0.2667) x 78.5398 Area of sector = 21.0014 sq cm
So the area of a sector of a circle with radius of 5 cm and an angle of 96 degrees is approximately 21.0014 square centimeters.
2) What is the minor diameter of screw thread SQ 62 x 10.5 with depth clearance of 0.12 mm?
3) How many un-numbered divisions on the British chasing dial?
Explanation:
To find the total surface area of a cube, you can use the formula:
Surface Area = 6 x (side length)^2
In this case, the side length of the cube is 25 cm. So we can plug in this value into the formula:
Surface Area = 6 x (25)^2 = 6 x 625 = 3750 cm^2
So the total surface area of the cube is 3750 cm^2. It's
