Unformatted text preview: N5: Statics Problem: A person of mass m walks across a beam of mass M. The beam is held
up by two supports, one at each end. What is the force exerted by the left
support as a function of where the person stands on the beam? A 1kg rock is suspended by a massless
string from one end of a 1m measuring
stick. What is the weight of the measuring
stick if it is balanced by a support force at
the 0.25m mark? Concept Test 1. by massless string from one end of a 1 meter
A 1kg rock is suspended0.25akg
2. the mass of the measuring stick if it is balanced by a
measuring stick. What is0.5 kg
support force at the 0.25m mark?
3. 1 kg
4. 2 kg
5. 4 kg
1. 0.25 kg
6. impossible to determine
2. 0.5 kg
3. 1 kg
4. 2 kg
5. 4 kg
6. impossible to determine Problem: A drawbridge has length L, width D, and mass M. It is held in a
horizontal position by two chains that make an angle with the horizontal.
What is the tension in the chains?
Simplify the geometry by taking D ≪ L ...
