Determine (a) the value of α so that the resultant of the three forces is to be vertical, and (b) the magnitude of the resultant force. Lastly (c) what are the components of the resultant force when resolved about the w and ν axis?(Figure 1)Block 1, of mass m1, is connected over an ideal (massless and frictionless) pulley to block 2, of mass m2, as shown. Assume that the blocks accelerate as shown with an acceleration of magnitude a and that the coefficient of kinetic friction between block 2 and the plane is μ. Find the ratio of the masses m1/m2. Express your answer in terms of some or all of the variables a, μ, and θ, as well as the magnitude of the free-fall acceleration g.Part C: find force in AD chain for equilibrium.

- Part C. When angle = 11°, how large must the coefficient of static friction be so that the black can be attached 12 cm from the left end of the stick without causing it to slipA dancer is standing on one leg on a drawbridge that is about to open. The coefficients of static and kinetic friction between the drawbridge and the dancer's foot are μs and μk, respectively. n⃗ represents the normal force exerted on the dancer by the bridge, and F⃗g represents the gravitational force exerted on the dancer, as shown in the drawing.(Figure 1). For all the questions, we can assume that the bridge is a perfectly flat surface and lacks the curvature characteristic of most bridges. Before the drawbridge starts to open, it is perfectly level with the ground. The dancer is standing still on one leg. What is the horizontal component of the friction force f⃗? (Express your answer in terms of some or all of the variables n, μs, and/or μk.) (Figure 2). The drawbridge then starts to rise. The dancer continues to stand on one leg. The drawbridge stops just at the point where the dancer is on the verge of slipping. What is the magnitude f of the frictional force now?

(b) Determine the tensions in the two cords. (left and right)(c) If the tabletop were smooth, would the tensions increase, decrease, or remain the same? Possible answers:The tensions in the both cords will remain the same. The tension in the left cord will decrease while the tension in the right cord will increase. The tension in the left cord will increase while the tension in the right cord will decrease.Blocks of mass m1 and m2 are connected by a light string over a pulley, as shown.
