A homogeneous meter stick has a mass of 130 g and has it center of gravity at 50.00 cm. The fulcrum has been moved from its center of gravity to the point 62.00 cm. A rock is placed at the 95.00 cm mark on the meter stick. What is the mass of the rock

The a992 steel rod bc has a diameter of 50 mm and is used as a strut to support the beam. determine the maximum intensity w of the uniform distributed load that can be applied to the beam without risk of causing the strut to buckle. take f.s. = 2 against bucklin

Which one of the following research methods can show cause and effect

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).
