Physics of a Pendulum Impact Tester

on

Hello, I would like to use a Pendulum Impact Tester to produce various impact forces, such as the one shown here, https://www.agrintl.com/wp-content/uploads/2016/03/IT_2_redesign.pdf. The data sheet provides the following info: • Weight of Pendulum: 0.6kg • Length of Pendulum to Center of Striking Face: 11.56in • Maximum Swing: 135° • Maximum Energy: 2.5J

How would I go about determining the Maximum Force this system could apply? Could I use the following deviations of Newton’s Second Law and the Conservation of Energy?: Newton’s Second Law States that: F = m * a a = v/t F = m* (v/t) Conservation of Energy states that Energy Before = Energy After PE = KE *PE = mgh *KE = (1/2)mv2 *mgh = (1/2)mv2 * v=SQRT(2gh) F = m * (SQRT(2gh)/t) Need to find h *mgh = (1/2)mv2 *h = (1/2) * (v2/g) F = m * (SQRT(2g((1/2) * (v2/g)))/t) Need to find t *Velocity = Distance / Time *v=h/t *t=h/v *t= (1/2) * (1/g) *v F = SQRT((m((1/2)mv2))/((1/2)((1/2)(1/g)*v)2)) F = SQRT((KEm)/((1/2)((1/2)(1/g)v)2))
Need to find v KE = (1/2)mv2 *v=SQRT(KE/(1/2)m) F = SQRT((KEm)/((1/2)((1/2)(1/g)( SQRT(KE/(1/2)m)))2))
This simplifies to F = 2g*m *This can’t be correct? Wouldn’t the force depend more on just gravity and the mass of the pendulum?

Thanks in advance for any support
