Hi, sorry my replies are few and far between. Dead week is aptly named. I've learned that I can treat the force at the pin as just one resultant force, perpendicular to the throwing arm. So I have three equations and three unknowns. I found the angle by taking the arctan(vertical distance...
I chose the sign convention to be positive in the counter-clockwise direction. Here's my work. Other than direction of the forces on the x direction, I think it's correct. Would you mind looking it over?
Thanks for the heads up. I've attached the pdf file. I've also added one more equation:
ΣMPin = (1435 N)(60.71") - (FYAxle)(49.59") + (FXAxle)(33.23") + (114 N)(40.5") = 0.
So this gives me four equations and four unknowns. This will allow me to solve for the X and Y forces at the pin and...
Homework Statement
The goal is to calculate the static forces in the throwing arm of the trebuchet when it's pinned as shown in the image. The counterweight is equal to 1435 Newtons. The mass of the arm is equal to 114 Newtons. Dimensions are shown in inches. The pin is in double shear...
