5.      (2 points) True or False: Physiology, biomechanics and psychophysics are considered in NIOSH lifting equation.

4.      (2 points) True or False: Time studies are used to assess unnecessary motions involved in tasks.

3.      (2 points) True or False: When determining how many machines should be assigned to an operator the following equation is used: n = (l+m) / (l+w); l  refers to the operator service time to machine (loading and unloading parts).

(4 points) For the four pictures below, select the potential application of the dimensions being measured

(4 points) For the four pictures below, select which of the dimensions is being measured

(2 points) True or False: When calculating the standard deviation of the difference between elbow height and knuckle height, we must have a correlation coefficient between the two measurements.

(2 points) True or False: Biomechanics should be used in work design because engineers need to ensure that task demands do not exceed human capacity.

(2 points) True or False: The NIOSH lifting equation can be used to calculate recommended weight limits for both standing and seated lifting tasks.

(2 points) True or False: One reason why a standing workstation may be preferable over a sitting workstation is because it can relieve spinal disc pressure.

(2 points) True or False: A pinch grip is used for holding a heavy object.
