5- A wooden block with a density of 1 is floating completely submerged at the interface of two liquids with densities of 02 an 03. If V3 is the volume of the block in the lower liquid and V₁ is the total volume, show that: V3 V1 = (P₁-P2) (p3 - Pz) Q2 Q3

B2

Answer are nearly around 2237N ,0 N and and 1887N

4. A nylon [E = 360 ksi; v= 0.4] rod (1) having a diameter of dl = 2.50 in. is placed inside a steel [E = 29,000 ksi] tube (2) as shown in Figure P3.7. The inside diameter of the steel tube is d2 = 2.52 in. An external load P is applied to the nylon rod, compressing it. At what value of P will the space between the nylon rod and the steel tube be closed? Nylon rod (1)- Steel tube (2)

I was wondering in the hydrodynamics how i can determine Cp in the pressure ressistance (coefficient pressure). so the total ressistance will be Rt= Rf+Rp. Given in Coefficients it will be: Ct=Cf+Cp now they say Cp in % of the friction coefficient (Cf). Ct=(1+k)*Cf with 1+k the formfactor. so the total ressistance will be Ct=Cd*1/2*ρ *v^2*S (wetted area m^2, v= velocity in m/s and ρ= 1025 kg/m3 for salt water) kan you explain me how to calculate the Cd in the total resisstance?

Question 4: A machine of 540 kg is bolted at the middle of two parallel simply supported steel beams. The clear span of the beam is 2.4 m. The moment of inertia of the cross-section of each beam is I = 4.2×10¯6 mª. The Young's modulus of the steel is E 200 GPa. When the machine is operating, it will generate a vertical force P(t)=Posinot. When the machine runs at 300 rpm, Po= 1500 N. Neglect the weight of the beams and assume 2% viscous damping in the system. Determine the amplitude of steady-state deflection of the beams at their midpoint when the machine runs at 300 rpm. machine 1.2 m = 1.2 m Steel beams

Problem 1. The rectangular area in figure (a) is split into three equal areas and arranged as shown in figure (b). Calculate the area moment of inertia about the x-axis for (a) and for (b). How many times larger is the area MOI for (b) compared to (a)? Use h = 200 mm and b = 60 mm. h 1123---x 2---x (a) (b)
