A Simply supported beam is 4m long with a udl of 4.3kn/m. the material of the beam has a modulus 0f 9000 N/mmsq determine the deflection of the beam at ;
1.The centre of the beam
2.At 1.33m from one end of the beam

What precautions should you take to prevent injuries when dealing with heavy loads?

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

Fluids at rest possess no flow energy. a)- true b)- false
