We've got a 10# load hanging from the boom of the NS4 crane. The boom is at a 35 degree angle and the boom line makes a. 20 degree angle with the horizontal. First we have to find the OTM- see Don't tip over the crane. We know the force is 10#, and D is the shortest distance from the pivot point to the. Cos 35 = D load. We've...

Trebuchet- pile driver- catapult. Roosevelt HS STEM PROGRAM. Tension in the boom line. Method of Joints and Free Body Diagrams. Torque- - -Moment of Force. Would you like to build a drawbridge? How about an archway? With a set of BRIDGE BEAMS and your imagination you can build almost anything. Here's a cable-stayed bridge- like the new Tillikum Crossing. The bricks are the counter-weights. This excavator has a pivoting arm with a scoop at the end. You could build a crane that could raise small loads.

Trebuchet- pile driver- catapult. Roosevelt HS STEM PROGRAM. Tension in the boom line. Method of Joints and Free Body Diagrams. Torque- - -Moment of Force. Compute the Mechanical Advantage of pulleys with 1, 2 or 4 parts of line. Use the formula to find the Center of Gravity for an off-centered load. Decide on a value for RM/OTM and compute the counter weight and its distance from the fulcrum. For a given load and boom angle, compute the Tension in the boom line using the Sine function.
Cantilever Bridges
