Q4:A smooth 5 kg collar shown in fig 1, fits loosely on the vertical shaft. if the spring is unstrched when the collar is in the position A, determine the speed at which the collar is moving when y=lm ,if (a) it is released from rest at A and (b)it is released at A with an upwared velocity Va=6m/s. 0.75 m wwww k =3N/m (a) Figure 1.

7.11. The U-bend shown in Fig. 7.23 is connected to the rest of the piping system by flexible hoses. The inside diameter of the pipe is 3 in. The fluid flowing is water, and its average velocity in the pipe is 50 ft/s. The gauge pressure at point 1 is 30 psig and at point 2 is 20 psig. What is the horizontal component of the force in the support? Flow Flexible hoses →→ Flow Support FIGURE 7.23

QUESTION 2 The truss carries the loads as shown in Figure 2. The truss is supported by pin at A and smooth roller support at G. (a) Determine the reactions at pin A and smooth roller support at G.
