Figure 2. The effects of changes in the angle of the dynamometer force plate relative to the line of motion of the test limb on force recorded during strength testing. Here the dynamometer is no longer in line with the line of force of the hip motion, (i.e. the angle has increased from 0o). If Ѳ is equal to 30o, and a subject produces 100 Newtons (N), then 116.3 Newtons will be transmitted to the dynamometer (C = 100 Newtons/cosine 30o).
