water density =1000kg/m^3 woodblock density = 620 kg/m^3 pressure above the water = P atm Using Fluid Statics and Bernoulli Equation 1-what is the weight of w to insure successful plugging? 2- what force to be applied to the block to lift it and allow water to drain

Solve using paper:PROBLEM 19: The horizontal top of a concrete column is subjected to the system of forces shown. Represent the resultant of all forces as a force R at point O

Figure 3 shows a truss where P = 40 kN and Q = 27 kN. The force reaction at A in the y-direction is FAy = 29 kN up and the force reaction at G in the y- direction is FGy = 38 KN up. In the question that folows, select ihe anawer that in choneat to the tre vale. What is the magnitude of the force in member KL in units of kN? O 38.7 O 58.7 52.0 453

DESIGN DESCRIPTION To construct a warehouse, the frame system shown in Figure 1 has been adopted. As an engineer, your task is to analyse the mid frame, highlighted in RED. Column 3 Column 1 Beam 1 Columb 2 Slab 1 Beam 1 Slab 2 Beam 2 Beam 3 Column 2 5 m 5 m 5 m Column 3 Column 1 8 m (a) Transfer of self-weight of Slabs 1 and 2 to surrounding beams (simplified case) Beam 1 Figure 1 A warehouse frame system The detailed information of the structural components is provided as follows: Slabs 1 and 2 are made of in-situ cast reinforced concrete and have a thickness of 150 mm (Figure 2). For simplicity, we assume that half the weight of each slab is transferred to Beam 1 (as shown in Figure 2). In addition, a water tank full of water with a weight of 1042 kg (1000 L of water plus weight of the tank) will be installed in the middle of Beam 1 (Figure 2). All the beams are made of reinforced concrete and have a standard size of 225 mm x 600 mm. Note that the density of reinforced concrete is…
