The angle between the two concurrent forces is 90° and their resultant is 25ooN. The resultant makes an angle of 45° with one of the force. Determine the magnitude of each force.
The suitcase has a mass of 15kg, and a constant friction of 15N opposes the motion. She starts with an initial speed of 0 and moves the suitcase a distance of 20m. Find the speed of the suitcase at the end of the path.
The guy wires AB and AC are attached to the top of the transmission tower. The tension in cable AB is 8.6 kN. Determine the required tension T in cable AC such that the net effect of the two cables is a downward force at point A.

The total number of effective exposures per unit of advertising medium depends on the region reached. In Louisiana, the number of effective exposures is 70,000, 100,000 and 75,000 for television, radio and direct mail, respectively.
Cork is used for sealing sparkling wine bottles. Aside from friction, why not use rubberbto seal wine bottles. (Hint: think about the force exerted by the pressure inside and how does that deform each material) Be sure to use poissons ratio in the..
Water boils at room temperature of 25 degrees celsius when the pressure is 3.17 kPa (abs). Express this as a vaccum gage pressure (in mmHg) if atmospheric pressure is 101 kPa. Provide details of work to get a good rating.
What is the total moment M due to the force F about point O. Assume that moments acting counterclockwise about point O are positive whereas moments acting clockwise are negative.
