Ms Bowen is curious about what type of tape is the strongest and decides to develop an experiment to find out. She decides to test packing tape, painters tape, and duct tape. She takes two pieces of cardboard and tapes them together using each type of tape. Then she hangs weights on the bottom to see which one will hold the most weight. When the tape lets loose, she records the mass that was hanging from the bottom. Use this information to answer questions about this experiment on this and the next page. The independent variable is: The dependent variable is:

A 30kg barrel of oil is sitting in a holding container consisting of two walls one at an angle of 60o from the horizontal, and the other wall at 40o from the horizontal. What are the normal forces acting on the walls – N1 and N2? Draw a free body diagram and a resolved free body diagram.

PRO BLEM 2: A TRICKY STRUT An orange strut of length l is connected to a wall via a pi vot at the bottom. An additional (blue rope) also connec ts the strut to the wall attached at an angle 01. A load of weight W is hanging from the strut; the load makes an angle 02 with the strut as shown in the diagram. In order to stabilize the system, and additional force needs to be applied. That force, which is labeled C in the diagram, makes an angle p with respect to the strut as shown. What is o?

A 0.50-mm-radius fishing line made of nylon is 100 m long when no forces are applied. A fish is hooked and pulls with a tension force Of 250 N. What is the elongation?

Include a free body diagram please.

A person exerts a horizontal force of 190 N in the test apparatus shown in the figure. Find the horizontal force that his flexor muscle exerts on his forearm. Number i Units 0.34 m Flexor muscle M 190 N 0.054 m Elbow joint

<→X CO|| 国 A 65-kg man is halfway up a 15-m ladder that is resting against a smooth, frictionless wall. If the ladder has negligible weight and it makes an angle of 55° with the ground, find the normal force from the wall acting on the ladder. Note: there is a force of friction acting on the foot of the ladder. A. Draw a FBD for the ladder [Select ] Diagram A Diagram B Diagram C Diagram D Diagram E B.
