Experiment 2: Skeletal Muscle ABSTRACT Frog skeletal muscle is used as an animal model to study muscle contraction. The objectives of this experiment is to demonstrate the physiological responses of skeletal muscle to electrical stimuli using frog gastrocnemius‚ to understand twitch‚ summation‚ tetanus and fatigue‚ to investigate the relationship between initial tension and force of contraction‚ to explore the differences between human and frog skeletal muscle. The threshold voltage is 0.4V. The

CEMB 121 MECHANICS OF MATERIALS LABORATORY EXPERIMENT (NO.2 (a)) SHEAR FORCE I SUMMARY Shear Forces occurs when two parallel forces act out of alignment with each other. For example‚ in a large boiler made from the sections of sheet metal plate riveted together‚ there is an equal and opposite force exerted on the rivets‚ owing to the expansion and contraction of the plates. The shearing force (SF) at any section of a beam represents the tendency for the portion of the beam on one side of
