Early escalators had stairs made of wood â which happens to burn, unfortunately. One of the most notorious escalator accidents in history occurred on November 18th, 1987, when a fire fanned by drafts in Londonâs Underground subway network killed 31 people.
Preheat your oven to 475 degrees F. Move your bottom round to a roasting pan, and place a meat thermometer into the thickest part of the beef. Step 3. Roast your bottom round at 475 degrees F for 30 minutes. Then, reduce the heat to 350 degrees F and continue roasting. Monitor the meat thermometer for your desired cooking level. Anything below an internal temperature of 130 degrees F is rare. Do not roast to an internal temperature of more than 140 degrees F or your roast will be medium, not medium rare.
Step 1. Preheat your oven to 325 degrees Fahrenheit for a pot roast from the round; 425 degrees for a pot roast from the chuck; and 350 degrees for a pot roast from the rib. The weight and type of roast determines the cooking time; you should cook a roast until its internal temperature is between 135 and 150 degrees F.For instance, a 2- to 3-lb. rump roast cooks for 1 Â½ to 2 hours to medium-rare doneness, the Cattlemen's Beef Board and National Cattlemen's Beef Association website advises.tep 4. Remove the pot roast from the oven when it is 5 to 10 degrees below the recommended final internal temperature. Cover the roasting pan loosely with a tent of aluminum foil and let the roast stand for 15 to 20 minutes. The internal temperature of the roast will rise another 5 to 10 degrees.
