1.

Determine the internal axial force, shear force, and moment at point F of the frame.

AF = 0, VF = 750 lb, MF = 750 lb-ft
AF = 1500 lb, VF = 0, MF = 4500 lb-ft
AF = 0, VF = 1500 lb, MF = 4500 lb-ft
AF = 750 lb, VF = 0, MF = 750 lb-ft

2.

The work platform supports an 80-kg man having a mass center at G. Determine the axial force, shear force, and bending moment at point E of the telescopic column AB due to the load of the man only.

AE = 785 N C, VE = 0, ME = 785 N-m
AE = 785 N C, VE = 392 N, ME = 0
AE = 785 N T, VE = 392 N, ME = 0
AE = 785 N T, VE = 0, ME = 785 N-m

3.

Determine the internal axial force, shear force, and moment at point E of the oleo strut AB of the aircraft landing gear.

AE = 9.33 kip C, VE = 8.00 kip, ME = 80.0 kip-in.
AE = 11.11 kip T, VE = 6.67 kip, ME = 66.7 kip-in.
AE = 9.33 kip T, VE = 8.00 kip, ME = 80.0 kip-in.
AE = 11.11 kip C, VE = 6.67 kip, ME = 66.7 kip-in.

4.

A force of 500 N acts at the top of the two-member frame. If the members are in smooth contact with one another at A, B, and C with no fasteners, determine the shear force developed at a horizontal section through point D of the support. Also, what are the axial force, shear force and moment at point E?

VD = 250 N, AE = 250 N, VE = 333 N, ME = 316 N-m
VD = 333 N, AE = 333 N, VE = 250 N, ME = 267 N-m
VD = 333 N, AE = 333 N, VE = 250 N, ME = 200 N-m
VD = 250 N, AE = 250 N, VE = 333 N, ME = 267 N-m
