ICURE B-42 Problem 25 26. BIO Tra action After a skiing accident, your leg is in a cast and sup- ported in a traction nit Newton's third law, t force on the leg.) Let the mass m be 2.27 kg devi of the force F exerted by the leg on the small pulley. (By he small pulley exerts an equal and opposite 29. Small pulley 30.0 130.0° in FIGURE 6-43 Problem 26

Answer 1

for the hanging block , force equation is given as

T₂ = mg

T₂ = 2.27 x 9.8 = 22.25 N

since the rope is same

T₁ = T₂ = 22.25 N

parallel to the leg , force equation is given as

F = T₁ Cos30 + T₂ Cos30

F = (22.25 + 22.25) Cos30

F = 38.5 N
