One easy way to reduce heating (and cooling) costs is to add extra insulation in the attic of a house. Suppose the house already had 15 cm of fiberglass insulation in the attic and in all the exterior surfaces. If you added an extra 8.0 cm of fiberglass to the attic, then by what percentage would the heating cost of the house drop? Take the single story house to be of dimensions 10 m by 15 m by 3.0 m. Ignore air infiltration and heat loss through windows and doors.

B/ A journal/shaft of 60 mm diameter rotates at 3200 rpm. The journal is supported by a short hydrodynamic bearing of length L = D/3. The distance between the center of bearing and the center of shaft is 0.018 mm and the ratio of journal radius to the clearance is (). The radial load on the bearing is 9.3 kN. The lubricant is SAE 30, and the operating temperature of the lubricant in the bearing is 80°C. Calculate: (i) the minimum and maximum lubricant film thickness, (ii) the maximum lubricant pressure at bearing, and (iii) the friction power losses.
A steel (E = 210 GPa) bar is subjected to a force of F=2500 N. Where l=300 mm, a=200 mm, diameter of the bar d=20 mm. The bar is made of AISI 1050 cold-drawn steel Sut-690 MPa, Sy-580 MPa.
