how are force sensor readings related to the size of the pull exerted on the force sensor hook by the rubber bands

The frictional force between two surfaces in contact does not depend on?   a. whether the surface are stationary or not b. the normal force pressing them together c. whether a lubricant is used or not d. the area of the surfaces in contact

A super-light horizontal beam supports a 460-N canister as shown in the figure. What is the net force applied by the wall to the horizontal beam? Express your answer in Newtons and round it off to the nearest ones. 5.00 m 3.00 m 4.00 m Om

Consider a group of people trying to stay afloat after their boat strikes a log in a lake. Construct a problem in which you calculate the number of people that can cling to the log and keep their heads out of the water. Among the variables to be considered are the size and density of the log, and what is needed to keep a person's head and arms above water without swimming or treading water.

Verity that the force in the elbow joint in Example 9.4 is 407 N, as stated in the text.

A box rests on a steel surface. Four sides of the box are made of aluminum, and the other two sides are coated with Teflon. Each panel in Figure 6.8 shows a pair of experiments. In each pair, decide which experiment requires the larger tension force to move the box and therefore has the higher maximum static friction force. FIGURE 6.8

Let AI represent the density of aluminum and Fe that of iron. Kind the radius of a solid aluminum sphere that balances a solid iron sphere of radius rFe on an equal-arm balance.

A black aluminum glider floats on a film of air above a level aluminum air track. Aluminum feels essentially no force in a magnetic field, and air resistance is negligible. A strong magnet is attached to the top of the glider, forming a total mass of 240 g. A piece of scrap iron attached to one end stop on the track attracts the magnet with a force of 0.823 N when the iron and the magnet are separated by 2.50 cm. (a) Find the acceleration of the glider at this instant. (b) The scrap iron is now attached to another green glider, forming total mass 120 g. Find the acceleration of each glider when the gliders are simultaneously released at 2.50-cm separation.

Roofs are sometimes pushed off vertically during a tropical cyclone, and buildings sometimes explode outward when hit by a tornado. Use Bernoulli's principle to explain these phenomena.

In a force system if all the forces pass through single point, it is called as, a. Parallel forces b. Coplanar force system c. Concurrent force system d. Collinear force system
