The hammer / anvil impact force is a useless number if you are interested in the effect on the SUT I used a similar method to find out why lugs 108 and 110 in the figure below broke when the calculated strength was about 100 lbs and the force was from a spring similar to the spring in a ball point pen

If damping effects from air resistance and friction are negligible equations concerning the frequency and period of the the pendulum as well as the length of the string can be calculated The period equation is T = 2π√ L/g The frequency equation is f = [√ g/L ]/2π The length equations are L = g/ 4π2f2 and L = gT2/4π2

The test involves letting the pendulum go from a set height and calculating the force when it impacts an object held in a vice at the bottom of the arc Force values need to be calculated for releasing the pendulum at 5 through to 45 degrees in 5 degrees incremements and with the weight of the pendulum changing from 1 2 3kilos respectively

The momentum of the pendulum just before it impacts the test specimen will be equal to the momentum of the pendulum after the impact plus the momentum transferred to the test specimen After determining the momentum transferred to the test specimen you can calculate the force exerted on it provided you know the length of time that the specimen

Energy conservation says the the force transmitted must equal the kinetic energy applied The formula mv^2 /2 will provide the energy The velocity can be obtained through the vertical drop How this is translated will depend on the weight of the object it is hitting and also the if it is fixed Alan 1 Scott Brickner

After impact the angle which the pendulum arm went through will be recorded on your device which you can use to see how much energy was left in the pendulum just calculate the height the centre of gravity of your arm went through after impact and then calculate the potential energy = mass gravity const height reached

Therefore work is equal to force multiplied by distance W=Fd W = F d Because force is a component of work and an impact is the conversion of energy into work you can use the equations for energy and work to solve for the force of an impact The distance traveled when the work is accomplished by an impact is called the stop distance

We can use this formula for the period of a pendulum to calculate its frequency f = frac {1} {T} = frac {1} {2pi}sqrt {frac {g} {L}} f = T 1 = 2π1 Lg Here f f is the frequency of the pendulum For amplitudes greater than 15 degree 15° the pendulum s period also depends on the moment of inertia of the suspended mass
