The formula is short and relatively simple; **Punch Force (PF) = Area x Shear Strength**, where Area is the cross-sectional area of the material being punched away and Shear Strength is the shear strength of the particular material being punched.

- Assume that the acceleration of the punch for an experienced boxer is 30 m/s².
- Multiply his weight by the acceleration of the punch ( 80 kg × 30 m/s² ) .

- The result is 2400 N or 540 pounds-force.

FF=(fracture stress)× area =16×10×3. 5×10=**5.** **6×10 N**.

1 answer. The correct option is (b) **5.6 x 10 ^{4} N**.

The average hitting power of most people is between **60-170 PSI**, with outliers at both ends of this range. There is considerable debate as to how much training can contribute to a person’s ability to hit the ball vs.

To calculate the impact force, **divide the kinetic energy by the distance**.

To calculate the impact force, **divide the kinetic energy by the distance**.

To calculate the impact force, **divide the kinetic energy by the distance**.

- Formula. T = P x Th x C. T = Required pressure in tons.
- Example. .050 CR Steel, 1/2 Hd; Cutting edge of 12 linear inches T = 12 x 0.050 x 3
- Constants. Aluminum Soft-1 T4/T6-1

What force is required to punch a ½ inch hole in 3/8 thick sheet when the sheet’s ultimate shear strength is 42,000 psi? Troubleshooting: The force required to punch a ½ inch hole in a 3/8 thick board is **24,740 lbs**.

If a hole of diameter “d” is punched in metal of thickness “t” then **the force required to punch a hole is equal (where τu = shear strength of the sheet material)**

The formula we use: **F_Pierce = C x t x S** where C is the perimeter of the blank, t is the thickness and S is the shear strength, which I usually use as 80 percent of the tensile strength.< /p>

The kinetic energy of a punch varies greatly. While beginners may only be able to summon a meager 37.5 joules of energy, experts can deliver **over 400 joules**, an amount that’s about the same as being shot with a pistol!

A study of 70 boxers found that elite fighters could punch **an average of 776 pounds**. Another study of 23 boxers showed that elite fighters could punch more than twice as hard as novices, with the hardest hitter generating nearly 1,300 pounds of force.

Ngannou himself holds the current record for the world’s hardest punch, having measured a punch power of **129,161 units on a PowerKube**, which measures the power of a punch based on a variety of different factors, including Power, speed and accuracy.

**v = m/s**. The kinetic energy just before impact is equal to its gravitational potential energy at the drop height: K.E. = J.

If you hit a wall at a certain speed, you have **kinetic energy Ekin=12mv2, where m is your mass and v is your speed**. The wall will slow you down with very little space (and time), so the power is extremely high.

Multiply mass times acceleration.

The force (F) required to move an object of mass (m) with an acceleration (a) is given by the formula **F = m x a** specified . So force = mass multiplied by acceleration.

Calculate the required pressing force to produce the following component. Sheet thickness 2mm. Material is brass. **Press force = cutting force + stripping force** =100800 + 20% 100800 =120960 N =120,960 KN.
