The 25-kg bar has a centre of mass at G.If it is supported by a smooth peg at C,a roller at A and cord AB, determine the reactions at these supports.
A 4 m diameter sphere is embedded in insulation. The sphere contains a liquid-ice mixture maintained at 0 deg C. The ambient temperature surrounding the insulation is 25 deg C.
Calculate the crack length after cycles and subjected to a cyclic stress normal to the crack
Determine the molecular weight of a poly(ethylene-propylene) with a degree of polymerization of 25,000 given that 20% of the mers (by number) are ethylene and 80% are propylenel.
Assuming that the bomb is perfectly insulated what is the temperature of the air in the bomb at the end of filling process? Assume air is an ideal gas with constant specific heats in a ratio Cp/Cv = γ = 1.4 and constant R= 287 J/kg K.
Find the compression ratio, cutoff ratio, the thermal efficiency, the mean effective pressure, and the P -v and T-s diagrams clearly showing all corners.
Determine the resultant of the three forces F1 = 2.0i + 3.3j - 2.6k; F2 = - i + 5.2j - 2.9k; and F3 = 8.3i - 6.6j + 5.8k, which are concurrent at the point (2, 2, -5.). The forces are in Newton's and the distances are in meters.
What are the knot values? How many different curves is the B-spline curve composed of? Expand the B-spline curve equation to get the separate equations of the curves in b.
