Dear eng, Pls ans quickly Thanks
Q3
A roof truss member is subjected to four external forces acting at joints of a truss as shown in
Figure Q3.
(b)
(c)
Determine the force of P when a is equal to 60° which creates total moment of zero at
joint A.
Using force P obtained from Q3(a), replace all given forces by an equivalent resultant
force at joint C and sketch the direction of the forces.
Determine the smallest force of P acting on the truss if the resultant couple moment at
joint C and D has the same magnitude.
