Two shuttle looms (A and B), running at the same picks per minute, have the same mass of sley and associated system for beat-up. The crank radius (\( r \)) and the eccentricity ratio (\( e \)) of the looms are \( r_A = 10 \, \text{cm} \); \( e_A = 0.5 \); \( r_B = 6 \, \text{cm} \); \( e_B = 0.4 \). The ratio of the beat-up force of loom A to that of loom B (rounded off to 1 decimal place) is ______.
