Determine the resultant force magnitude, direction, and its angle from the x-axis for force components F1 & F2, components F2 & F3, and components F3 & F4.

Two muscles in the back of the leg pull upward on the Achilles tendon, as shown in the figure below. (These muscles are called the medial and lateral heads of the gastrocnemius muscle.) F₂ = 205 N F₁ = 205 N 26° 26° Find the magnitude (in N) and direction (in degrees counterclockwise from the dotted line) of the total force on the Achilles tendon. XN magnitude direction X counterclockwise from the dotted line 410 25.45 What type of movement could be caused by this force? O This force can raise the heel of the foot. This force can twist the ankle to the left or right. This force can turn the foot to the left or right. This force can lower the heel of the foot.                     Needs Complete typed solution with 100 % accuracy.

Use the rectangular component method to solve the fol- lowing problems. Determine the magnitude R of the re- sultant of the forces and the angles 8, By, and 8, between the line of action of the resultant and the positive *-, y-, and z-coordinate axes for F2 = 200 Ib F, = 100 Ib 70
