A cable supports a load of 40 kg/m uniformly distributed along the horizontal and is suspended from the two fixed points A and B located as shown.  CALCULATE THE MINIMUM TENSION

The signboard truss is designed to support a horizontal wind load of 660 lb. If the resultant of this load passes through point C, calculate the forces in members BG and BF. The forces are positive if in tension, negative if in compression. 660 lb Answers: BG= BF= i i -8' B E 8' G +4'H 9' 9' b 9¹ lb lb

Find the reactions at the fixed support A given the distributed loads shown. (+)+ 1 = (d) 1 = su A y 4 ft. 200 lb/ft 150 lb/ft + 3 ft B

Please show clear work and free body diagram if possible

The structure shown below is a simplified tower crane. It carries a shipping crate suspended from B that has a weight of 116 kN . The main jib DCB (in green) has a weight of 17 kN concentrated in the center of the beam. This is pinned to the main body at D and is supported by a cable that is routed through pulleys at F and G and is attached to a concrete counterweight J. The main body AEFG (in yellow) is fixed to the ground at A.   Various geometry: h1= 26.5 m h2= 3.9 m h3= 5.1 m l1= 12.8 m l2= 17 m l3= 4.3 mm θ= 57.6 degrees   Assumptions :  The main body AEFG can be considered massless. The cable CFGJ is massless. The pulleys at F and G can be considered massless, frictionless, and of negligible diameter. All bodies are considered rigid.   Questions:  Determine the weight of counterweight J in order for the main jib DCB to be horizontal. Determine the magnitude of the x and y components of force at pin D. Determine the reactions at fixed support A.

Please answer ASAP

Beam AC is loaded with the distributed load shown, where the magnitude of the distributed load is w, = 700 lb/ft at A and 300 lb/ft at C. The support at B is fixed and the support at C is a roller. Determine the reactions at the beam supports. The solution to this problem must include a free-body diagram of the beam and a sketch of the coordinate system used to apply EF = 0 and EM = 0. wo 300 lb/ft A В 5 ft 7 ft
