Chapter 9: Q9-6Q (page 230)

Can the sum of the torques on an object be zero while the net force on the object is nonzero? Explain.

Short Answer

Expert verified

Yes, it is possible for the sum of the torques on an object to be zero while the net force on an object is nonzero.

Step by step solution

01

 Step 1: Understanding translational equilibrium

A body is supposed to be in translational equilibrium if there is no resultant force. This suggests that the addition of all the forces working on the body should be equivalent to zero.

02

Example explains that the sum of the torques on an object is zero while the net force on the object is nonzero

Consider the example of a meter stick, and exert equal forces upward along the \( + y\) direction on the opposite ends of the stick. Thus, the net torque about the center of the stick will be zero, whereas the net forces will be along the \( + {\rm{y}}\) direction.

(II) At depths of 2000 m in the sea, the pressure is about 200 times atmospheric pressure\(\left( {{{\bf{P}}_{\bf{a}}}{\bf{ = 1}}{\bf{.0 \times 1}}{{\bf{0}}^{\bf{5}}}\;{\bf{N/}}{{\bf{m}}^{\bf{2}}}} \right)\). By what percentage does the interior space of an iron bathysphere鈥檚 volume change at this depth?

A 25-kg object is being lifted by two people pulling on the ends of a 1.15-mm-diameter nylon cord that goes over two 3.00-m-high poles 4.0 m apart, as shown in Fig. 9鈥�86. How high above the floor will the object be when the cord breaks?

Three children are trying to balance on a seesaw, which includes a fulcrum rock acting as a pivot at the center and a very light board that is 3.2 m long (Fig. 9鈥�57). Two playmates are already on either end. Boy A has a mass of 45 kg, and boy B has a mass of 35 kg. Where should girl C, whose mass is 25 kg, place herself to balance the seesaw?

(II) One liter of alcohol \(\left( {{\bf{1000}}\;{\bf{c}}{{\bf{m}}^{\bf{3}}}} \right)\) in a flexible container is carried to the bottom of the sea, where the pressure is \({\bf{2}}{\bf{.6 \times 1}}{{\bf{0}}^{\bf{6}}}\;{\bf{N/}}{{\bf{m}}^{\bf{2}}}\). What will be its volume there?

(II) If 25 kg is the maximum mass mthat a person can hold in a hand when the arm is positioned with a 105掳 angle at the elbow as shown in Fig. 9鈥�74, what is the maximum force\({F_{{\bf{max}}}}\) that the biceps muscle exerts on the forearm? Assume the forearm and hand have a total mass of 2.0 kg with a CG that is 15 cm from the elbow, and that the biceps muscle attaches 5.0 cm from the elbow.
