Problem #7 (20 points): Two wooden planks, each 15 mm thick and 200 mm wide, are joined by the glued finger joint as shown below. The joint consists of several interlocking “fingers” that are 25 mm wide and d long. Glue is applied to both surfaces of the “finger”, but not to the end. One of the glued surfaces is indicated in the figure. An axial load of P = 4 kN is applied to the planks. In addition, the ultimate shear strength (Sus) of the glue is 900 kPa. Glue 25 mm P 200 mm P Calculate the smallest allowable length of the "fingers", d, to avoid failure. Put units on all answers! 25 mm

Part B As shown, a space truss is the frame for a building's awning. (Figure 2) Three ball-and-socket joints at A, B, and E support the frame. If a force of F = {120i+ 330j} N is applied at point D, what are the forces in each member? Indicate a tensile force as a positive value and a compressive force as a negative value. Express your answers numerically to three significant figures in newtons separated by commas. • View Available Hint(s) It vec ? FDA. FDc. FDB. FCA. FCB. FCE = Submit

Q2
Problem 1 The structure shown below supports a vertical load P = 100 N. The sloped wall at A is frictionless (slope 0 = 54°) and the structure is anchored at G with a frictionless pin. Note that the structure consists of three members, ABEG, BCD, and ED. Ignore their weights. The angle ß = 55.3°. Find all the forces acting on member ABEG and draw them on the figure on the next page. Draw arrows in the correct directions and label them with magnitudes.

How do i find the force of Ay and Fy. Can this probelm be solved woth method of joints. Also what is the C or T, x and y components and the load of each member. Also when you put the answer can you put it like it is on the image please.
Dear expert solve correctly all parts Including last one
(a)The device shown in figure 5 is designed to apply pressure when bonding laminate to each side of a countertop near an edge. If a 10 N force is applied to the handle, determine the force which each roller exerts on its corresponding surface. (b) The aircraft loading gear consists of a spring and hydraulically loaded piston and cylinder D and the two pivoted links OB and CB (figure 6). If the gear is moving along the runway at a constant speed with the wheel the supporting the stabilized constant load of 24 kN, determine the total force which the pic at A supports. (c) The tower for a transmission line is modeled by the truss shown in figure 7. The crossed members in the center section of the truss may be assumed to be capable of supporting tension only. For the loads of 1.8 kN applied in the vertical plane, determine the forces induced in members AB and CD. (d) The jib crane supports a load of 750 lb from the trolly which rides on the top of the jib. Determine the internal…
