Cross Sectional Area And Length Tension Relationship Experiments have shown that the change in length (Δl) depends on only a few variables. as already noted, Δl is proportional to the force f and depends on the substance from which the object is made. additionally, the change in length is proportional to the original length l 0 and inversely proportional to the cross sectional area of the wire. The greater the number of cross bridges attached to the actin filaments, the larger the contraction force . the length tension curve below summarizes the relationship between muscle length and tension during force production. it is important to note that two joint muscles undergo active and passive insufficiency during simultaneous movements.

Cross Sectional Area And Length Tension Relationship In order for a single muscle to generate the same force while maintaining such a high v max, the fibre length would have to be 76 mm (as for the ecrl to maintain the same v max) and the cross sectional area would have to be about 4.2 cm 2 (the sum of the two muscles' pcsas to maintain the same maximum force). Figure 26.2.1 26.2. 1: tensile stress on a rod. the ratio of the applied perpendicular force to the cross sectional area is called the tensile stress, σt = f⊥ a (26.2.1) (26.2.1) σ t = f ⊥ a. the ratio of the amount the section has stretched to the original length is called the tensile strain, εt = δl l0 (26.2.2) (26.2.2) ε t = δ l l 0. Where is the change in length, the applied force, is a factor, called the elastic modulus or young’s modulus, that depends on the substance, is the cross sectional area, and is the original length. table 3 lists values of for several materials—those with a large are said to have a large tensile stiffness because they deform less for a given tension or compression. The pillar’s cross sectional area is 0.20 m 2 and it is made of granite with a mass density of 2700 kg m 3. find the compressive stress at the cross section located 3.0 m below the top of the pillar and the value of the compressive strain of the top 3.0 m segment of the pillar.
