Concept

Problem: Determine the magnitudes of the forces P, R, F required for equilibrium of point O.A. R = 238 N, F = 181.0 N, P = 395 NB. R = 1340 N, F = 740 N, P = 538 NC. R = 419 N, F = 181.0 N, P = 395 ND. R = 408 N, F = 504 N, P = 1099 N

FREE Expert Solution

The equilibrium condition:

F=0

Let's start by expressing the forces P in Cartesian vector form:

P=P[-i-3j+3k(-1)2+(-3)2+32]=P[-i-3j+3k19]
