Concept explainers

Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

Question

Problems
1. Calculate the linear momentum of a belt drive, if the masses of both pulleys and
the belt are taken into consideration. The centre of gravity of each pulley is located
on the axis of rotation.
2. Figure shows a pulley with a rope running over it. A man holds one side of the
rope at A while a load, equal to the weight of the man, is attached to the other end
of the rope at B. What would happen to the load if the man starts climbing up the
rope with the velocity a relative to the rope? Neglect the weight of the pulley.

17. Under static or constant velocity conditions, the wheelchair will tip back- wards if the vertical projection of the combined center of gravity (CG) of the wheelchair and occupant falls behind the point of contact between the rear wheels and the ramp surfaces. As shown in Figure 5.12, the rearward tipover angle (0,) is determined by the horizontal distance (d₁) and the vertical distance (d₂) between CG and the wheelchair's rear axles. a) Using static analysis, derive the equation relating 0,, d₁, and d₂. b) Using the platform approach depicted in Figure 5.7, suggest a method for determining d₁. c) Assuming that d₁ and d₂ averaged 13 cm and 24 cm, respectively, for able-bodied individuals, what would 0, be? d) How would d₁ and d₂ change if the wheelchair occupant leaned forward instead of sitting back against the chair? How would 0, be affected by this postural shift? CG 0₁ T K-d? 30.5cm

Her foot pivots as a single structure about a single pivot in her ankle. When she stands on tiptoe, her foot pivots about her ankle. As shown in the foot diagram and the free-body diagram below, the forces on one foot are an upward force on her toes from the floor, a downward force on her ankle from the lower leg bone (called the Tibia), and an upward force on the heel of her foot from her Achilles Tendon. Suppose a 61.3 kg woman stands on one foot, on tiptoe, with the sole of her foot making a 25.0 degree angle with the floor, and with the distances are as shown in the figure.
