The left end of a spring is attached to a wall. When Bob pulls on the right end with a 200N force, he stretches the spring by 20 cm. The same spring is then used for a tug of war between Bob and Carlos. Each pulls on his end of the spring with a 200N force. How far does the spring stretch. Explain

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

You are participating in a basketball game and as you turn to recieve a ball, a 4 cm long section of your medical collateral ligament stretches to 4.09 cm as a result of a 1150 N tensile force. (100 cm = 1 m; 1 m^2 = 1,000,000 nm^2), (1 m^2 = 1,000,000^2 or 18 mm^2 = 0.000018 m^2). a) how much strain does the ligament withstand? b) how much strain potential energy does the ligament possess in this position if the stiffness value (k) is 9,000 N/m? c) if the ligament has a cross section of 18 mm^2, how much stress does the ligament withstand? Answer parts a-c. Show all work.

A 2.00-m-long, 1.00-mm-diameter wire is suspended from the ceiling. Hanging a 4.50 kg mass from the wire stretches the wire’s length by 1.00 mm. Use g = 10.0 m/s2. What is the stress in this wire, ____ ×107 N/m2? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

A person who weighs 744 N steps onto a spring scale in the bathroom, and the spring compresses by 0.510 cm.  What is the weight of another person who compresses the spring by 0.380 cm?

Calculate the shear force acting on the lumbar vertebra.  calculate the compressive force acting on the lumbar vertebra The GRF is 225 N. The GRF has a moment arm of 0.40 m relative to the vertebra axis of rotation. The weight of the trunk is 350 N. Wtrunk has a moment arm of 0.3 m relative to the vertebra axis of rotation. Fm is 300 N. Fm has a moment arm of 0.05 m relative to the vertebra axis of rotation.
