Give your answer in J. The net work output of a heat engine is the area contained within its path going in a clockwise direction on a P-V diagram. For this problem, the triangular area contained by the straight lines connecting A to B, B to D, and D to A. We can divide this triangle into two right angle triangles created by the horizontal dashed line at 2*10€ N/m². The area of a right angle triangle is A = b.hJ where A is the area in units of J, b is the base of the triangle in N/m², and h is the height of the triangle in m-3. The net work output is therefore the sum of the two triangular areas, W= A1 + Ag= 아어시 + bzh2) = (2.6 – 2) · 10° N/m² · (4 – 1) - 10-3 m³ + (2 – 1) · 10° N/m² - (4 – 1) · 10-3 W = 2.4 · 103 J
