Question
Please Explain
Three ropes pull on a knot shown in (Figure 1) . The knot is not accelerating. A partially completed force diagram for the knot is shown in the figure (Figure 2) . Use Newton's second law to determine the magnitudes of the forces that ropes 2 and 3 exert on the knot. Suppose that T1onK = 1000 N .
Determine the magnitude of the force that rope 2 exerts on the knot.
Express your answer to two significant figures and include the appropriate units.
Determine the magnitude of the force that rope 3 exerts on the knot.
Express your answer to two significant figures and include the appropriate units.
Explanation / Answer
Here net force on Knot is zero.
Fnety = 0
T2*sin(53) - T1 = 0
T2 = T1/sin(53)
= 1000/sin(53)
= 1252.14 N <<<<<<<----------Answer
Fnetx = 0
T2*cos(53) - T3 = 0
T3 = T2*cos(53)
= 1252.14*cos(53)
= 753.55 N <<<<<<<----------Answer
