You are working with a patient strengthening their scapula muscles for four weeks. You notices that the R scapula is excessively winging even after performing exercises for this length of time. You suspect the patient MAY have damage to which nerve? 

This special test determines if there is a subluxation of the shoulder joint and is measured by giving traction to shoulder joint. There may be a significant “dip” occurs resulting in a “one or two finger” measurement.

You are measuring elbow flexion to obtain goniometric measurements for ROM. The proximal arm of the goniometer is at the 

A W14x82 made with A992 steel is pinned at both ends and braced in the weak direction as shown. Determine the value of the controlling slenderness ratio Lc/r. Let L1 = 28 ft, L2 = 8 ft, and L3 = 20 ft.

Bending is about the x-axis of each member. Determine the value for G (that would be used for GA or GB in the alignment charts) at point F in the frame.Girders BF, CG and DH are W18 x 55 and have a length of L1 = 20 ft.Girders FJ, GK and HL are W24 x 68 and have a length of L2 = 36 ft.Columns AB, EF and IJ are W10 x 88 and have a length of L3 = 14 ft.Columns BC, FG and JK are W10 x 49 and have a length of L4 = 10 ft.Columns CD, GH and KL are W10 x 33 and have a length of L4 = 10 ft.

A W16 x 50 column is made from ASTM A572 Gr. 42 steel and has a length of 27 ft with Kx = 2.2 and Ky = 1.0. Determine the nominal compressive strength, Pn, for this column. Assume the shape is nonslender.

A W14x53 made with A992 steel is pinned at both ends and braced in the weak direction as shown. Determine the value of the controlling slenderness ratio Lc/r. Let L1 = 29 ft, L2 = 9 ft, and L3 = 20 ft.

A column is fabricated by welding a 1 x 18 plate to the left and right of a W14x53. Determine the moment of inertia about the y axis.

A W14x90 made with A992 steel is pinned at both ends and braced in the weak direction as shown. Determine the value of the controlling slenderness ratio Lc/r. Let L1 = 30 ft, L2 = 11 ft, and L3 = 19 ft.

A column will buckle in the direction corresponding to the smallest slenderness ratio.
