4. A spider builds its web in a window frame that is lying on the ground. It is supported by four main strands. Calculate the force of tension in strand 4 assuming the web is stable. The tensions in the other three strands are as follows: strand 1: 21 mN [N 20° E] strand 2: 16 mN [S 60° E] strand 3: 18 mN [S 40° W]

3. A uniform beam of mass 20 kg is suspended horizontally by a wall at one end and a cable that makes an angle of 0= 30° with the beam at the other end. The cable can sustain a maximum tension of 300 N before it breaks. a) What is the farthest distance from the wall (x) that a 10 kg mass can be suspended without the upper cable breaking? b) When x has this value what is the force exerted by the wall onto the beam? Wall 10 kg 10 m
L GAS A 48.0 kg sign hangs at the end of a bar where L = 3.10 meters in length. A cable attaches to the end of the horizontal bar and to a wall 2.60 meters above where the bar is attached to the wall. The bar has a mass of 12-kg. What is the tension in the cable? Give your answer in Newtons to 3 significant figures (no decimal places in this case).

Many caterpillars construct cocoons from silk, one of the strongest naturally occurring materials known. Each thread is typically 2.0 µm in diameter, and the silk has a Young's modulus of 4.0 x 10° N/m2. Assuming that there is no appreciable space between the parallel strands, how many strands N would be needed to N = strands make a rope 8.6 m long that would stretch only 1.02 cm when supporting a pair of 85-kg mountain climbers? Again assuming that there is no appreciable space between the parallel strands, what would be the diameter d of the rope? d = cm

Masses M1 and M2 are supported by wires that have equal lengths when unstretched. The wire supporting M1 is an aluminum wire 1.35 mm in diameter, and the one supporting M2 is a steel wire 0.4 mm in diameter. What is the ratio M1/M2 if the two wires stretch by the same amount? Young’s modulus for aluminum is 7 × 10^10 N/m^2and for steel 2 × 10^11 N/m^2. *
