Q.3) A 200-kg load is supported by the rope and pulley system shown. Pulley A has a mass of 4 kg and the mass of the rope is negligible. Assume the pulley is frictionless and treat pulley A as a particle. a) If ß= 10°, determine the magnitude of the applied force P and its direction (a) in order to keep the system in static equilibrium assuming 0° ≤ a ≤ 90°. b) Given 0° ≤ a ≤ 90°, find the range of ß angles for which the system can be in static equilibrium (write an inequality for the range assuming ß cannot exceed 90°).

Transcribed Image Text:Q.3) A 200-kg load is supported by the rope and pulley system
shown. Pulley A has a mass of 4 kg and the mass of the rope is
negligible. Assume the pulley is frictionless and treat pulley A as
a particle.
a) If ß= 10°, determine the magnitude of the applied force
P and its direction (a) in order to keep the system in static
equilibrium assuming 0° ≤ a ≤ 90°.
b) Given 0° ≤ a ≤ 90°, find the range of ß angles for which
the system can be in static equilibrium (write an inequality
for the range assuming ß cannot exceed 90°).
