Two forces F₁ = (2500 N, 62.0°) and F₂ = (1800, 150°) act on a stationary mass.
What force F3 (mag. & dir.) would be needed to keep the mass from moving?
Three forces F₁ = (800. N, 125°) F₂ = (550 N, 225°) F3 (1200, -25.0°) act on
stationary mass. What equilibrant force is required?
A 425 kg sign is suspended from the end of a massless strut as shown. What is
the tension in the cable holding up the strut up?

A 220 kg sign is suspended form the end of a massless strut 1.50 m long. A cable
running from the end of the strut to a point 2.25 m above the strut supports the
strut and sign. What is the tension in the cable?

A supertanker is being towed by two tugboats as a shown. The tensions in the
towing cables T₁ and T₂ are each 1.6x105 N and are directed at equal angles of
30.0° with respect to the tanker axis. If the tanker moves with a constant velocit
of 2.00 m/s (i.e. no acceleration), what is the drag of the water on the
supertanker's hull?
