6.2.2   Checking the loads to the timber beams
	The coils rest on two beams of 15 x 15 cm cross-section and a length of t = 140 cm. The loaded length from each coil is r = 90 cm. With the extension of (t - r) = 50 cm and the load of 4.5 t the necessary section modulus for each beam is taken from the diagram in Figure 16 with about 280 cm³. The beams have a section modulus of 513 cm³ (Table 1). Also the extension of 50 cm is well within permissible limits.
