Okay, hopefully I can describe this so that its understandable. I have a wooden rectangle that is 10" wide and 20" tall and 3" thick. It weighs about 6 or 7 pounds. Imagine it positioned so the the 10" end is facing the floor. I need to have it so that it rotates 90 degrees under motive power so...

A block of weight = 25.0 sits on a frictionless inclined plane, which makes an angle = 35.0 with respect to the horizontal, as shown in the figure. A force of magnitude = 14.3 , applied parallel to the incline, is just sufficient to pull the block up the plane at constant speed.What is , the work...

Dear Answerer! What are the formulas for calculating the magnetic force?How could we maintain the force of a permanent magnet?For lifting and holing up a weight by a permanent magnet, what are the formulas and sequences? If we need to have two permanent magnet with the same physical dimension but...

A crate of mass m (=10 kg) is placed at rest on a (frictionless) inclined plane, which has an angle (= 30 deg ) above horizontal 1. The force of gravity on the crate is? 2. The normal force on the crate is? 3. The net force on the crate is? 4. How long would it take the crate to slide 8 m...

If a vehicle has wheels and tyres with a rolling radius of 0.315m and the engine is producing a torque of 150nm at 4000 rev/min in fourth gear. (matching 4th gears have 30 (driver) and 29 (driven) teeth. Final drive gears have 20 (driver) and 88 (driven) teeth. am i correct in thinking final...
