Concept explainers
You are balancing a wrench by suspending it at a single point. Is the equilibrium stable, unstable, or neutral if the point is above, at, or below the wrench’s center of gravity? In each case give the reasoning behind your answer. (For rotation, a rigid body is in stable equilibrium if a small rotation of the body produces a torque that tends to return the body to equilibrium; it is in unstable equilibrium if a small rotation produces a torque that tends to take the body farther from equilibrium; and it is in neutral equilibrium if a small rotation produces no torque.)

- Answer yes or no to the following questions. (a) Is it possible to calculate the torque acting on a rigid object without specifying an axis of rotation? (b) Is the torque independent of the location of the axis of rotation?arrow_forwardWhen tightening a bolt, you push perpendicularly on a wrench with a force of 165 N at a distance of 0.140 m from the center of the bolt. How much torque are you exerting in newton-meters (relative to the center of the bolt)?arrow_forwardA force of F=(2.00i+3.00j) N is applied to an object that is pivoted about a fixed axle aligned along the z coordinate axis. The force is applied at the point r=(4.00i+5.00j)m. Find (a) the magnitude of the net torque about the z axis and (b) the direction of the torque vector .arrow_forward
- Assume a single 300-N force is exerted on a bicycle frame as shown in Figure OQ10.5. Consider the torque produced by this force about axes perpendicular to the plane of the paper and through each of the points A through E, where E is the center of mass of the frame. Rank the torques A, B, C, D, and E from largest to smallest, noting that zero is greater than a negative quantity. If two torques are equal, note their equality in your ranking. Figure OQ10.5arrow_forwardA 10.6 m long uniform ladder that weighs 428 N is resting against a very slimy wet moss covered wall that can be considered to be frictionless, as shown in the figure below. A firefighter that weighs 785 N is 4.64 meters up the ladder. The ladder is in static equilibrium. The normal force that the ground exerts on the ladder is? (enter your answer with three significant figures)arrow_forwardAn individual leans forwards to pick up a box of 100 N. The weight of his upper body has a magnitude of 450 N. The back is pivoting around the base of the vertebral column. Consider the back of the individual as a rigid bar that is controlled by a muscle with an angle of 12° (See picture, d = trunk-head distance = 1 m).a) Calculate the magnitude of muscle force required to lift the box.b) Calculate the magnitude of the force at the base of the vertebral column. Hints: For (a) solve the equilibrium of moments, i.e. what force is required in the muscle to balance out the moments acting around the base of the spine.For (b), solve the equilibrium of forces acting on the spine, including the muscle force you’ve just calculated, in x and y separately. There are two extra forces not shown in the diagram: x and y contact forces acting at the base of the spine. These are whatever is needed to keep the total forces acting on the spine = 0 (so the spine isn’t accelerating off in some…arrow_forward
- The center of gravity of Kelly's outstretched arm is located 21 cm from the axis of rotation in her shoulder. Her arm has a mass of 4.2 kg and is 56 cm long. Assuming the deltoid's force is horizontal, what is the magnitude of the force her deltoid muscle must exert on Kelly's upper arm so she can hold a 6.0 kg mass stationary 15 degree above the horizontal as shown? Her deltoid muscle attaches to her upper arm at a point 18 cm from her shoulder joint. 6 kg 15° 21 cm Fdeltiodarrow_forwardAn object can rotate but not exhibit no angular acceleration and no linear or translational acceleration. Such an object is in both translational and rotational equilibrium. What are the conditions for the object to be in static equilibrium? A vaulter holds a 29.4 -N pole in equilibrium by exerting an upward force U with her leading hand and a downward force D with her trailing hand as shown. Point C is the center of gravity of the pole where the 29.4 N acts.

The figure indicates the masses and positions of the structure’s various parts. The structure is mounted with two bolts, located symmetrically about the vertical member’s centerline, as shown.
