A unipennate muscle has a cross-sectional area of 10 cm2 and another cross-sectional area of 11 cm2. The angle of pennation for both cross-sectional areas is 30°. This muscle can produce a maximal isometric contraction force of 500 N. What is the stress during the maximal isometric contraction?

As seen in a us weather map, the h (or high) and l (or low) symbols indicate regions where surface air pressures are high or low, respectively, compared to surrounding areas. an h is plotted where the air pressure is highest and an l is plotted where the air pressure is lowest. proceeding outward and away from the center of a high pressure system, the air pressure "
