1) The three cables are used to support the 40 𝑘𝑔 flowerpot. Determine the force developed in
each cable for equilibrium.
2) Determine the magnitudes of F1, F2, and F3 for equilibrium of the particle.

3) If the two forces 𝑭1 = {100𝒊 − 120𝒋 + 75𝒌} 𝑁 and 𝑭2 = { −200𝒊 + 250𝒋 + 100𝒌} 𝑁
act at A, determine the resultant moment produced by these forces about point O. Express the
result as a Cartesian vector.
4) The towline exerts a force of 𝑃 = 6 𝑘𝑁 at the end of the 8𝑚-long crane boom. If 𝑥 = 10 𝑚,
determine the position 𝜃 of the boom so that this force creates a maximum moment about point
𝑂. What is this moment?
