Concept explainers
Propose a force standard different from the example of a stretched spring discussed in the text. Your standard must be capable of producing the sane force repeatedly.
To propose: a standard force that is different from the example of a stretched spring.
Explanation of Solution
Introduction:
The force acting on a stretched string can be calculated by calculating the stretch produced in the string. Here, we need to propose a force standard which is different than this stretched spring.
The above figure shows the arrangement of Pascal’s law. When a force is applied on the beaker A, the water level of beaker B rises by a height h .
The pressure acting on the Beaker is given as
So,
V is the volume of liquid raised in the beaker B. So by using this standard, we can measure the forces acting on beaker A.

- Some people modify cars to be much closer to the ground than when manufactured. Should they install stiffer springs? Explain your answer.arrow_forwardHanging from the ceiling over a baby bed, well out of baby’s reach, is a string with plastic shapes, as shown here. The string is taut (there is no slack), as shown by the straight segments. Each plastic shape has the same mass m , and they are equally spaced by a distance d , as shown. The angles labeled describe the angle formed by the end of the string and the ceiling at each end. The center length of sting is horizontal. The remaining two segments each form an angle with the horizontal, labeled . Let T1 be the tension in the leftmost section of the string, T2 , be the tension in the section adjacent to it, and T3 be the tension in the horizontal segment. (a) Find an equation for the tension in each section of the string in terms of the variables m,g , and . (b) Find the angle in terms of the angle . (c) If =5.10 , what is the value of ?(d) Find the distance x between the endpoints in terms of d and .arrow_forwardPhysics students design an experiment to measure assorted coefficients of friction using a set-up similar to the one shown (not drawn to scale). A small balloon containing sand with a combined mass of 98.2gg is suspended with an ideal string of length 86.6cmcm, forming a simple pendulum. The pendulum is released from an angle of 41.4∘∘ with the vertical, and it collides with a block of mass 333gg located where the pendulum string becomes vertical. Because the balloon weighted with sand is soft and deformable, the collision is totally inelastic. The block slides for a distance of 30.8mmmm before coming to rest. a) Calculate the speed, in meters per second, of the sand-filled balloon at the instant prior to the collision. b) Calculate the speed, in meters per second, of the block at the instant following the collision. c)arrow_forward
- An archer must exert a force of 345 N on the bowstring shown in Figure (a) such that the string makes an angle of ? = 40.0° with the vertical. If the applied force is replaced by a stretched spring as in Figure (b) and the spring is stretched 27.0 cm from its unstretched length, what is the spring constant?arrow_forwardA block of mass ? = 300 g is released from rest from the top of a frictionless ramp. At the bottom of the ramp, a spring with a force constant ? = 400 N/m is fixed, as shown in the figure. If the maximum compression of the spring is 10 cm, determine the angle θarrow_forwardA spring is attached to a block with a mass of 2.33 kg. The block is set on a rough horizonal surface, and you pull horizontally on the other end of the spring, steadily increasing the force. As soon as the spring stretches 0.126 m beyond its equilibrium length, you notice the block starts to move. If the spring constant is 75.8 N/m, what is the coefficient of static friction between the block and the surface?arrow_forward
