Example 3: A 20 kg block hangs from the set of cables shown be- low. Find...
3.) A uniform beam, mass 15.0 kg. hangs motionless, supported by three cables as shown in the figure. A 12.0 kg mass hangs from a point one- quarter of the length of the beam from the left end. T=? What is the tension in the vertical cable attached at the left end of the beam? m
Example 4a: Find the magnitude of the maximum horizontal force F that can be applied to the block but will not move it. v=0 m, 35 kg u, = 0.50 m1 Apply Newton's Laws: Force Diagram(s) M,-35 nety O ts (35%)) 1715 At f 95.0 N is applied to a 60.0 kg nt 12
A mass m = 180 kg hangs from a horizontal ceiling by two cables, one has a length of 3.4 m, and the other has a length of 4 m. The two cables subtend an angle of 90° at the mass. What is the tension in each cable? N (small value) N (large value)
The system in the figure is in equilibrium. A concrete block of
mass 245 kg hangs from the end of the uniform strut of mass 38.5
kg. For angles ? = 26.5° and ? = 61.3°, find
(a) the tension T in the cable and the
(b) horizontal and (c)vertical
components of the force on the strut from the hinge.

The system in the figure is in
equilibrium. A concrete block of mass 245 kg hangs from the end of
the uniform strut of mass 50.3 kg. For angles φ = 20.5° and θ =
54.9°, find (a) the tension T in the cable and the (b) horizontal
and (c) vertical components of the force on the strut from the
hinge.

After rounding second base, a baseball player with a mass of 77 kg slides into third base. The coefficient of kinetic friction between the player and the ground is 0.42. What is the magnitude of the friction force acting on the player? If it takes 1.3 s for the player to come to a rest at the base, what was his velocity when he initiated his slide? Suppose you are pulling a 4.2-kg block across a rough, horizontal surface with...
The system in the figure is in equilibrium. A concrete block of mass 156 kg hangs from the end of the uniform strut of mass 65.2 kg. For angles o = 21.5° and 0 = 45.7°, find (a) the tension I in the cable and the (b) horizontal and (c) vertical components of the force on the strut from the hinge.

At a construction site, a 68.0 kg bucket of concrete hangs from
a light (but strong) cable that passes over a light friction-free
pulley and is connected to an 85.0 kg box on a horizontal roof (see
the figure (Figure 1)). The cable pulls horizontally on the box,
and a 47.0 kg bag of gravel rests on top of the box. The
coefficients of friction between the box and roof are shown. The
system is not moving.
Find the friction...
A 2.0 kg ball hangs in an elevator as shown. The elevator has a downward acceleration of 2.5 A. Draw a free body diagram for the ball. In your diagram, draw the vectors to scale. (For example, a 2N force vector should be twice as long as a 1N force vector.) 60* 90 B. what is the total force on the ball? 772 a2.5 C. Find the tension force in each of the two ropes. D.
