On a day when the temperature is 20.0°C, a concrete walk is poured in such a way that its ends are unable to move.
(a) What is the stress in the cement when its temperature is 50.0°C on a hot, sunny day?
(b) Does the concrete fracture? Take Young's modulus for concrete to be 7.00 × 109N/m2and the compressive strength to be 2.00 × 107N/m2.
Using the kinematic equation, prove that if two balls are released simultaneously from table, one with zero velocity and the other with a horizontal velocity, they would both reach the ground at the identical time.
what is the minimum work by the force p to move the 8-kg block to the top of the incline of uk0.4? compare this with
It is hard, so then you get a heavy piece of iron and put the wood on top of that. You hold the iron and start pounding. Why is it easier now to get the nail into the wood?
