forces (making AB represent 8 tons), and find that BC represents M and CAthe resultant of the first pair. Next we resolve CA into components parallel to Nx and Ny, and find that CD and . Ceiling … DA represent Ny and Nx respectively.The forces on the boom being three innumber (the load, Q, and P), they mustbe parallel or concurrent, and becausetwo (the load and Q) are concurrent,all must be; thus the line of action ofP is determined. So we may draw theforce triangle EFGE for the three…
