Part of riding a bicycle involves leaning at the correct angle when making a turn, as seen below. To be stable, the force exerted by the ground must be on a line going through the center of gravity. The force on the bicycle wheel can be resolved into two perpendicular components—friction parallel to the road (this must supply the centripetal force) and the vertical normal force (which must equal the system’s weight). (a) Show that (as defined as shown) is related to the speed vand radius of curvature rof the turn in the same way as for an ideally banked roadway—that is, =tan1(v2/rg) . (b) Calculate for a 12.0-m/s turn of radius 30.0 m (as in a race).
Jamal and Dayo are lifting a large chest, weighing 207 lb, by using the two rope handles attached to either side. As they lift and hold it up so that it is motionless, each handle makes a different angle with respect to the vertical side of the chest (Fig. P5.76). If the angle between Jamals handle and the vertical side is 25.0 and the angle between Dayos handle and the vertical side of the chest is 30.0, what are the tensions in each handle? FIGURE P5.76
The drawing below shows a person whose weight is W = 552 N doing push-ups. Assume L1 = 0.871 m and L2 = 0.391 m. Calculate the normal force exerted by the floor on each hand, assuming that the person holds this position.
In the figure, block M2 is sitting on a table and is connected by mass-less chords to block M1 and to a vertical wall. The coefficient of static friction between M2 and the table is Us=0.60. Block M1 has a mass of 8 kg. The angle made by the chord and the wall is 55 degrees. What minimum mass must block M2 have in order to remain stationary and not slide?
When a gymnast performing on the rings executes the iron cross, he maintains the position at rest shown in figure (a). In this maneuver, the gymnast’s feet are off the floor. The primary muscles involved in supporting this position are the latissimus dorsi (“lats”) and the pectoralis major (“pecs”). One of the rings exerts an upward force Fh on a hand as shown in figure (b). The force Fs is exerted by the shoulder joint on the arm. The lats and pecs major muscles exert a total force Fm on the arm. Using the information in the figure, find the magnitude of the force Fm for an athlete of weight 750 N. Hint Fh = 750/2 N.
The figure below shows a human arm that weighs 41.10 N. The arm is extended outward and is motionless. The gravitational force Fg on the arm acts at point A, a distance of 0.2900 m from the shoulder joint, which is represented by point O. The shoulder pushes down and to the right on the humerus bone of the arm with a force Fs at point O, at an angle ? as shown. The deltoid muscle pulls back on the arm toward the shoulder with a tension force Ft. This tension force acts at a point 0.08000 m to the right of point O, and it is directed up and to the left, at a 12.00° angle with respect to the horizontal. An arm is extending horizontally to the right with a cutout that shows muscles in the upper arm. A horizontal dashed line extends along the bottom of the muscles and another along the top. Point O is labeled at the left end of the arm on the lower horizontal line. An unlabeled point lies 0.080 m horizontally to the right of point O. Point A lies 0.290 m horizontally to the right of point…

A 10.0-kg monkey climbs a uniform ladder with weight 1.20 × 102 N andlength L = 3.00 m as shown. The ladder rests against the wall and makes an angle of θ = 60.0° with the ground. The upper and lower ends of the ladder rest on frictionless surfaces. The lower end is connected to the wall by a horizontal rope that is frayed and can support a maximum tension of only 80.0 N. (a) Draw a force diagram for the ladder. (b) Find the normal force exerted on the bottom of the ladder. (c) Find the tension in the rope when the monkey is two-thirds of the way up the ladder. (d) Find the maximum distance d that the monkey can climb up the ladder before the rope breaks. (e) If the horizontal surface were rough and the rope were removed, how would your analysis of the problem change? What other information would you need to answer parts (c) and (d)?
On a particle of mass m = 20gr, three forces F1, F2 and F3 act in the plane of the paper. The forces F2 = 4N, F3 = 3 N and F1 is unknown as indicated in the figure.

The alpha angle of the direction of the force F3 is 300°
