- PROBLEM: Determine the forces in each member using any methoddiscussed in your theory of structures/mechanics. Using Software is notallowed. Show complete solution and tabulate your answers indicatingwhether it is compression or tension. Use Pn = 205 kN, Po = Zero. a) From the Problem and the image , Design one tension member, use either a double angle of a wt section. Check its adequacy using 1 line of bolts (three bolts in a line spaced at 75mm on centers) Assume a bolt diameter from 16-22mm. Use A 36 for all steel. Neglect block shear.please very urgent The bank in the figure is thought that a person is sittingthe force exerted on the board as 300 NIt is given.

- An aquarium tank holds salt water (RD 1.015) to a depth of 2.9 metres and has sides inclined at 75o to the horizontal. An access door A-B, measuring 1.1 metres by 1.1 metres, is pivoted at the base of the door (B) and held shut by a bolt at the top of the door (A). What is the tensile force in the bolt at point A.What are the reactions at a pin and bracket support in three-dimensional space? Answer with the number of force components and the number of couples.Consider the truss shown in the figure, built from three struts attached by three pins. The truss supports a downward force of F = 1,250 N applied at the point B. Assume the mass of the truss is negligible, the pins are frictionless, and the supports at A and C are also frictionless. (a) Assuming ?1 = 25.0° and ?2 = 49.0°, what are nA and nC? (Enter the magnitudes in N.) nA= NnC= N (b) The force any strut applies on a pin must be directed along the length of the strut as a force of tension or compression. What are the directions of the forces that the struts exert on the pins joining them? strut AB on joint A: strut AB on joint B: strut BC on joint B: strut BC on joint C: strut AC on joint A: strut AC on joint C: Find the force of tension or of compression (in N) in each of the three struts. bar AB Nbar BC Nbar AC N
- I need to draw a free body diagram and the solution m2=88kgA 25kg wooden plate is held in place by two strings attached to the ceiling and the wall. The string attached to the ceiling makes an angle 40o with the horizontal and the string attached to the wall makes 90o with the wall. Determine the force in each string (DONT ANSWER THIS PROBLEM). ANSWER ONLY THE PROBLEM IN THE ATTCHED IMAGE, COMPLETE SOLUTION PLEASE.A cylinder rests on a bar and a wall in the way indicated in the figure. The cylinder weighs 500 kgf and the bar 100 kgf. If all surfaces are smooth, determine the reactions at supports A and B of the bar.
- Two weights are connectedby a very light, flexible cord that passesover an 80.0 N frictionless pulley of radius0.300 m. The pulley is a solid uniformdisk and is supported by a hookconnected to the ceiling (Fig.).What force does the ceiling exert on thehook?A rubber cylinder R of length L and cross sectionalarea A is compressed inside a steel cylinderS by a force F that applies a uniformly distributedpressure to the rubber (see figure).(a) Derive a formula for the lateral pressure pbetween the rubber and the steel. (Disregardfriction between the rubber and the steel, andassume that the steel cylinder is rigid when comparedto the rubber.)(b) Derive a formula for the shortening δ of therubber cylinder.By what distance h does the cage shown in thefigure move downward when the weight W is placedinside it? (See the figure.)Consider only the effects of the stretching of thecable, which has axial rigidity EA =10,700 kN. Thepulley at A has a diameter dA = 300 mm and the pulleyat B has a diameter dB = 150 mm. Also, the distanceL1 = 4.6 m, the distance L2 = 10.5 m, and the weightW = 22 kN. Note: When calculating the length of the cable, include the parts of the cable that go around thepulleys at A and B.
