3. Determine the resultant of the three forces acting on the dam and locate its intersection with the base AB. For good design, this intersection should occur within the middle third of the base. Does it? Sim. F 8,000 N W 27 kN P 15 kN 8m G3 21m.

Find the support reaction components of the fixed point O. The distance between B and A is 220 mm and the force was is 110 N acts purely in the y~z plane

Cantilever beam AD is supported at A. A crossbar 2 m in length is welded at its center to the beam at C. Lengths AB, BC, and CD each are 2 m long. Find: (1) FAX, the x-component of FA, the resultant force at A (2) FAy, the y-component of FA (3) MAmag, the magnitude of the resultant couple moment at A Express your answers as Newtons and Newton-meters. F1 a1 2 m 2m F2 1m 1 m V Answer all numeric solutions with five significant figures. F1 = 28.2 N a1 = 64.1 deg a2 F2 a2 2 m F2 = 32.5 N a1 F1 a2 = 33.9 deg

The beam is made from a soft linear elastic material having a constant EI. If it is originally a distance  from the surface of its end support, determine the length a that rests on this support when it is subjected to the uniform load w0, which is great enough to cause this to happen.

If the force in member C is -4.3 kip, what is the force in member D? A Type your answer...

В A B C The system above is comprised of two-force members AB and AC, supporting a vertical force at point A. Assuming the system is drawn to scale and is in equilibrium, which of the following best describes the nature of the forces in members AB and AC? a) AB is in tension AC is in compression b) AB is in compression AC is in compression c) AB is in tension AC is in tension d) AB is in compression AC is in tension

TEXT:A planar construction is composed of two beam elements and two axial rods. These arejoined with frictionless joints, as indicated on the sketch. The structure is applied an outer concentrated load P=8kN in node G and a downwardevenly distributed load q=4kN/m between junctions A and D. The beam ABCD and EFG are torque rigid,while the axial rods BF and CF only absorb forces in the direction of the rods. A) Calculate the rod forces and for the external given load effect.B) Calculate the bearing reactions for the external given load effect.

What is the normal force at point A and the reaction at point B given thr static friction of 0.85?
