A 70 kg painter is painting the wall of a building. He stands on a horizontal board of length 4.5 m and mass 15 kg, suspended from vertical ropes attached to each end. If the painter stands 1.9 m from one end of the board, what would the tensions in the ropes be? tension in rope nearer to the painter tension in rope further from the painter

A scaffold of mass 44 kg and length 5.1 m is supported in a
horizontal position by a vertical cable at each end. A window
washer of mass 73 kg stands at a point 1.5 m from one end. What is
the tension in (a) the nearer (relative to the
person) cable and (b) the farther (relative to the
person) cable?

4. An 80-kg man stands in an elevator. What is his apparent weight when 1) the elevators stationary, IT) the elevator accelerates up at 2 m/s?. III) the elevator accelerates down at 2 m/s IV) the elevator cruises up at constant velocity of 1 m/s. A) Draw a free body diagram of the man labeling the two forces (n and weight) acting on him. B) Write Newton's 2nd law, just including the vertical components. C) Put the forces n...

In Figure (a), a uniform 44.4 kg beam is centered over two rollers. Vertical lines across the beam mark off equal lengths. Two of the lines are centered over the rollers; a 9.31 kg package of tamale is centered over roller B. What are the magnitudes of the forces on the beam from (a) roller A and (b) roller B? The beam is then rolled to the left until the right-hand end is centered over roller B (Figure (b)). What...

One end of a meter stick is pinned to a table, so the stick can rotate freely in a plane parallel to the tabletop. Two forces, both parallel to the tabletop, are applied to the stick in such a way that the net torque is zero. The first force has a magnitude of 2.00 N and is applied perpendicular to the length of the stick at the free end. The second force has a magnitude of 6.00 N and acts...

A gymnast with mass 42.0 kg stands on the end of a uniform balance beam as shown in the figure. The beam is 4.50 m long and has a mass of 230 kg (excluding the mass of the two supports). Each support is 0.590 m from its end of the beam. In unit-vector notation, what are the forces on the beam due to (a) support 1 and (b) support 2?

A uniform beam of mass my and length L hinged on the right supports a worker of mass my at a distance d' from its right end. A rope attaches to the left end of the beam at an angle . a) [5 pts) Reproduce this sketch and show all relevant forces acting on the beam. (You may simplify the drawing of the man - a stick figure will do, or a box.) b) [12 pts) Write the three equilibrium...
