Hi, i have a question.. I need to make a "bumper project" as shown in figure. I have all the geometric information about system and also know weight and energy which is transferred. I need to calculate the support reaction but i can not convert the energy to the force without "impact time". (F * t = m * V ) Also, i m not sure is there any reaction force on the supports because it s a pin connection. Is it possible to calculate F???
