The power required to machine metal is related to the cutting force (Fc) and the cutting speed. For a turning operation, you have selected an HSS (high speed steel) tool and turning a hot-rolled free-machining steel. Your depth of cut is fixed at 0.150 inches. The diameter of the workpiece is 1.00 inch. a) Estimate the cutting force Fc when the material removal is 2 cubic inch per minute and the spindle is rotating at 400 rpm. Specific cutting energy for free-machining steel is 0.5 hp-min/inch3. [ Select ] b) What will be the power needed at the spindle

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.

Asteel wire of 2 mm diameter is fixed between two points located 2 m apart. the tensile force in the wire is 250n, if its density of steel is given by 7830 kg/m3 the fundamental frequency of vibration hz? ?
