The thermal conductivity of a sheet of rigid, extruded insulation is reported to be k = 0.029 W/m-K. The measured temperature difference across a 25-mm-thick sheet of the material is T₁ T₂ = 12°C. (a) What is the heat flux through a 3 mx 3 m sheet of the insulation, in W/m²? (b) What is the rate of heat transfer through the sheet of insulation, in W? (c) What is the thermal resistance of the sheet due to conduction, in K/W?

Choice the correct answer of the following statements: 1. The power transmitted of two pulleys connected by an open belt or crossed belt is a) directly proportional to their diameters; b) inversely proportional to their diameters; proportional to the square of their diameters; c) directly d) inversely proportional to the square of their diameters. 2. Two pulleys of diameters d1 and d2 and at distance x apart are connected by means of an open belt drive. The length of the belt is: a) π/2 (d: + d₂) 2x + (d: + dz)/4x; b) n/2 (d₁-dz) 2x + (di-dz)/4x; c) n/2 (d: +d₂) 2x + (di-d₂}/4x; d) π/2 (d₁-də) 2x + (d: +d₂)²/4x. 3. In a cone pulley, if the sum of radii of the pulleys on the driving and driven shafts is constant, then: a) open belt drive is recommended; b) cross belt drive is recommended; c) both open belt drive and cross belt drive are recommended; d) the drive is recommended depending upon the torque transmitted. 4. Due to not slip of the belt, the power transmitted of the belt drive:…
Please answer 3, 4, 5, 6, 8, 9, 10, 12 1 is 0, 2 is 0, 7 is point A, 11 is 2. I included a picture of someone who solved but they were mostly incorrect. Please do not answer if the solution set I provided with the incorrect answers was you. I appreciate the attempt, but the solutions for 3, 4, 5, 6, 8, 9, 10, 12 were marked wrong, so unless you have different answers, please do not submit the same incorrect solution set. The wheel is attached to the spring. The mass of the wheel is m=20 kg. The radius of the wheel is 0.6m. The radius of gyration kG=0.4 m. The spring’s unstretched length is L0=1.0 m. The stiffness coefficient of the spring is k=2.0 N/m. The wheel is released from rest at the state 1 when the angle between the spring and the vertical direction is θ=30°. The wheel rolls without slipping and passes the position at the state 2 when the angle is θ=0°. The spring’s length at the state 2 is L2=4 m. (1) If the mass center G is set as the origin (datum), the gravitational…
