Problem 2/21
2/22 The unstretched length of the spring of modulus k =
1.2 kN/m is 100 mm. When pin P is in the position 0
30°, determine the x- and y-components of the
force which the spring exerts on the pin. (The force
in a spring is given by F = kx, where x is the deflec-
tion from the unstretched length.)

si 9. A 1.65 kg box rests on a plank that is inclined at an angle of 68.0° above the horizontal. The upper end of the box is attached to a spring with a force constant of 18.0 N/m, as shown in the figure. If the coefficient of static friction between the box and the plank is 0.28, what is the maximum amount the spring can be stretched and the box remain at rest? m f60 ssf60 ssico ss$60 ssf60** ssf60 ssf60 ssf60 ssf60 ssfossf60 ssf bood ssf60 ssf60 ss ] …………¶¶¶õõ‰¶¶¶¯¯¯ ¶ 50 ssf60 s f60 ssf60 ssf60 ss£60 SS sf60160 ssf60 ssf60 ssf60ain f60 sf60 ssf60 ssf60 ssf60 ƒ60 ssf60 ssf60 ssf
A force of 15.0 N is required to stretch a spring a distance of 5.20 cm. What is the force constant of the spring, in units of N/m?
As shown below, a 3 kg block on a frictionless horizontal surface is attached to a cable and a 526 N/m spring. The block is in equilibrium (Fnet = 0) and the cable has a tension of 16 N. Determine the normal force on the block and how much the spring stretched. FN l=| x
Find the minimum diameter of a (50 m)-long nylon string that will stretch no more than (1 cm) when a load of (70 kg) is suspended from its lower end. Assume that the Young modulus equals to 3.51*10 N/m? 3.35 cm 3.53 cm 35.3 cm 33.5 cm

Two rods are identical in all respects except one: one rod is made from aluminum (Young's modulus 6.8 x 1010 N/m²), and the other from tungsten (Young's modulus 1.7 x 1011 N/m²). The rods are joined end to end, in order to make a single rod that is twice as long as either the aluminum or tungsten rod. What is the effective value of Young's modulus for this composite rod? That is, what value Ycomposite of Young's modulus should be used in Equation 10.17 when applied to the composite rod? Note that the change ALComposite in the length of the composite rod is the sum of the changes in length of the aluminum and tungsten rods.
Current Attempt in Progress To measure the static friction coefficient between a 2.53-kg block and a vertical wall, the setup shown in the drawing is used. A spring (spring constant = 467 N/m) is attached to the block. Someone pushes on the end of the spring in a direction perpendicular to the wall until the block does not slip downward. If the spring in such a setup is compressed by 0.0540 m, what is the coefficient of static friction? Number i eTextbook and Media Save for Later Units Attempts: 0 of 5 used Submit Answer
