Extensive review articles have identified major work-related physical risk factors of MSD such as repetitive movements, high-force demands, awkward or extreme positions, rapid work pace, extreme temperatures, insufficient recovery time, mechanical pressure concentrations, and segmental or whole-body vibration [ 6– 8].
The added lateral strength may lead to higher component force demands, producing premature yielding, and high story accelerations, causing damage to contents.
This was due to high tensile force demand, consequent contraction of the tapered nut and pullout.
Since this process is governed by the size principle, training to induce skeletal muscle hypertrophy demands high force in order to generate type II fibers in voluntary contraction.
However, emerging technologies such as micro air vehicles, and microrobotics in general, demand high force, high displacement, low mass actuators.
Its envisaged application is an electromagnetic vibration isolator that demands a high force level, combined with low spring stiffness, which yields a low resonance frequency.
In general, for hazard levels of 10%% in 50 years and 50%% in 50 years, the force demands are highest for the firm soil and lowest for soft soils.
In our recent study examining the effects of HRLF performance in aged rats [ 19], we observed median neuropathy that was greater than that seen in our past studies on young rats, even studies examining the consequence of a high force task rather than this moderate demand task [ 15, 16, 18, 20].
Red, high force; blue, low force.
Finally, additional class of SMA-based connequippedequipped with hourglass steel pins passing through the beam web is introduced, studied under cyclic loads, and examined when subjected to high levels of shear force demand.
As it is recommended to take long, smooth propulsive strokes [ 13], this shortened contact time with the handrim could result in higher force and rate of force application and thus be related to higher joint demands.
